CHAPTER I
INTRODUCTION
A. BACKGROUND
This world
is our Almighty God’s creation. He created this world with many things in it.
Earth as our place of living is the one example. Earth as the third planet from
the core of our Milky Way Galaxy –Sun-, is so special. Many inventions and
literatures say Earth is only planet that has large amount of water. Earth
saves large amount of Oxygen gases (O2). Oxygen helps us to do
respiration in our cells to create energy from metabolism process. The next is
because we have great power from Earth (gravity force), same pressure from
every way, so we have good position to live.
The other
reason is because of our nature. We have influence with animals and plants. We
have imperceptible chain with other creatures. Without them we cannot live.
This chain need many chemistry reactions, biology, and physic process. Social
relationship is another reason. Without another human, we cannot continue our
generation.
The
conclusion that we can take that our Almighty God is so great. We have great
Creator. But, sometimes we do not realize that.
Human is
one of many things that God created. God created human very different from the
other things that He created. Because human is very special creation. Why human
very special? Because God gave us mind. Just man that given by kindness mind.
God created the other creation
without
kindness mind. That is the reasons why human very different and special from
the other creation.
The other
reason why human very special, because human similar and as pictured as with
Himself. Why God created human similar and as picture as Himself? Jesus created
human similar and as picture as Himself, because He want we take care of the
other creation that He created.
The very
first divine creation that is earth which is now a place of life of all
mankind. many beautiful creations of god and not recognized by humans. one of
the customers, most people know that there's a rainbow at the end of the rain.
it is due to people's stories and stories in the Bible. man only knew that only
one type of rainbow but turns out there are many types of rainbows.
Rainbows,,
how your beautiful rainbow. red yellow and green in the blue sky .. and so on.
This is one song that tells children about the beauty of the creation of God
Almighty.
Rainbow is
able to bring up a very interesting scenery to be enjoyed with our eyes. shaped
like an arc in the sky. This is a testament to the beauty of the rainbow when
people are in love long time ago.

Ø Definition of Rainbow
A rainbow is an optical
and meteorological phenomenon that causes a spectrum of light to appear in the
sky when the Sun shines on to droplets of moisture in the Earth's atmosphere.
It takes the form of a single arc. Rainbows caused by sunlight always appear in
the section of sky directly opposite the sun.
The sky is the nature's
canvas on which she paints beautiful and ever changing pictures. Light itself
is her color and she uses it in various ways to create beautiful optical
phenomena. One such rare masterpiece of her creation is the fire rainbow. In
this article, I discuss some interesting fire rainbow facts and explore how
this phenomenon is created.
If you see a splash of
rainbow colors in the sky, with the whole thing looking like a multicolored
flame, then you have probably witnessed a fire rainbow. It is a rainbow type
phenomenon, in the sense that it has the colors of a rainbow but it is shaped
quite differently. It looks like a rainbow colored flame and hence the name
'fire rainbow'. When people see a picture of such a fire rainbow, some think
that it's a hoax and is a computer generated picture! Nothing could be far from
the truth. Let such people know that it is not an illusion created by
photoshop, but an actual documented meteorological event. The fire rainbow
facts that I talk about here will illuminate the actual nature of this optical
phenomenon.
The sighting of a fire
rainbow, unlike a rainbow, is not so common. It is supposed to be a very rare
phenomenon that a person could see once or twice in his lifetime. That too, if
he has his eyes trained at the sky to appreciate the art pieces put up there,
by nature. If you are on photography hunt to capture that rare sighting of a
fire rainbow, then you need to know when and how it occurs. It is just like the
hunter who must know when and where to look for his prey, the photographer must
know when and in what conditions can this phenomenon occur. During such
sightings, photography skills are actually tested.
Author Donald Ahrens in his text Meteorology
Today describes a rainbow as "one of the most spectacular light shows
observed on earth". Indeed the traditional rainbow is sunlight spread out
into its spectrum of colors and diverted to the eye of the observer by water
droplets. The "bow" part of the word describes the fact that the
rainbow is a group of nearly circular arcs of color all having a common center.
In a so-called
"primary rainbow" (the lowest, and also normally the brightest
rainbow) the arc of a rainbow shows red on the outer (or upper) part of the
arc, and violet on the inner section. This rainbow is caused by light being
refracted while entering the droplet, then reflected on the inside back and
refracted again when leaving the droplet. In a double rainbow, a second arc may
be seen above and outside the primary arc, and has the order of its colours
reversed (red faces inward toward the other rainbow, in both rainbows). This
second rainbow is caused by light reflecting twice inside water droplets. The
region between the first rainbow and the second is dark, and is known as
"Alexander's band" or "Alexander's dark band". The reason
for this dark band is that, while light below the primary rainbow comes from
droplet reflection, and light above the upper (secondary) rainbow also comes
from droplet reflection, there is no mechanism for the region between a double
rainbow to show any light reflected from water drops.
It is impossible for an
observer to manoeuvre to see any rainbow from water droplets at any angle other
than the customary one (which is 42 degrees from the direction opposite the
Sun). Even if an observer sees another observer who seems "under" or
"at the end" of a rainbow, the second observer will see a different
rainbow further off-yet, at the same angle as seen by the first observer. The
rainbow is not at a specific distance, but comes from any water droplets seen
at a certain angle with the Sun's rays. Thus, a "rainbow" is not a
physical object, and cannot be physically approached.
A rainbow spans a
continuous spectrum of colours; the distinct bands (including the number of
bands) are an artefact of human colour vision, and no banding of any type is
seen in a black-and-white photo of a rainbow (only a smooth gradation of
intensity to a maximum, then fading to a minimum at the other side of the arc).
For colours seen by a normal human eye, the most commonly cited and remembered
sequence, in English, is Newton's sevenfold red, orange,
yellow, green, blue,
indigo and violet (popularly memorized by mnemonics like Roy G. Biv). However,
colour-blind persons will see fewer colours.
This is a good question
to start thinking about the physical process that gives rise to a rainbow. Most
people have never noticed that the sun is always behind you when you face a
rainbow, and that the center of the circular arc of the rainbow is in the
direction opposite to that of the sun. The rain, of course, is in the direction
of the rainbow.
Rainbows can be caused
by many forms of airborne water. These include not only rain, but also mist,
spray, and airborne dew.
J All about rainbow
ü Form
an arc across the sky like a rainbow. Beautiful curved red, orange, yellow,
green, blue, indigo, violet. shortened to mejikuhibiniu rainbow. Each saw a rainbow,
one wonders, does the rainbow? why is there a rainbow? Here's a little
explanation as I can.
>
The ancients imagined, the rainbow is a bridge to nergeri dwarf. That said, at
the end of the rainbow there is a dwarf's treasure chest. Dongen dwarf treasure
at the end of the rainbow is told to answer the mystery of the rainbow. People
believe in fairy dwarf for thousands of years. No one can explain the mystery
of the rainbow with the right samapai in 1673. and until now we know "what
is a rainbow" is just beautiful beams of light are visible in our eyes :)
A question like this calls for an appropriate physical response. we know, the
formation of a rainbow by rain water. This is a problem in the first optically
clear discussed by Rene Descartes in 1637. Interesting historical account of
this is to be found in the book Carl Boyer, The Rainbow From Myth to
Mathematics. Descartes simplified the study of the rainbow by reducing it to a
study of a single droplet of water and how it interacts with light falling on
it.
He
writes: "Considering that this bow appears not only in the sky, but also
in the air near us, whenever there are drops of water illuminated by the sun,
as we can see in certain fountains, I immediately decided that it comes just
from the way in where the rays of light on action and pass this drops from them
to our eyes more. know that the round drops, as has been shown before, and saw
that if they are larger or smaller, arc appearance has not changed in any way,
I have idea to make a very big, so I can check better.
Descarte describes how he was holding
a big ball in the sun and see the sun reflected in it. He writes "I found
that if the sun comes, for example, from the sky marked AFZ
This was just an incident beam of light on water droplets
from the SA. As light enters the surface of the drop in A, it is bent
(refracted) a little and strike the inner wall of the drop in B, where it is
reflected back to C. As appears from the drop it is refracted (bent) again into
the direction CE. D is a measure of the deviation angle beam emerging from its
original direction. Descartes calculated this deviation for the red light beam
to about 180-42 or 138 degrees.
Ray drawn here is important because it is light that has the
smallest deviation angle of incidence of light on all the rain. This is called
the Descarte ataupelangi ray and lots of sunlight, as refracted and reflected
through the rain along the beam is focused. So that the light reflected diffuse
and weaker except near the direction of this rainbow ray. This concentration of
light near the minimum deviation that causes a rainbow arc.
The sun is so distant that we can, to a good approximation,
assume that the sun's rays can be represented by a set of all parallel rays
fall on a blob of water and the refracted, reflected internally, and refracted
again on emergence of droplets in a manner such as images.
A typical rain is spherical and therefore its effect on
sunlight is symmetrical about an axis through the center of the drop and the
light source (in this case the sun). Because of this symmetry, two-dimensional
illustration of the image served us well and complete picture can be visualized
by rotating the two-dimensional illustration of the symmetry axis. Symmetry of
the focusing effect of each drop like that every time we see the rain along the
line of sight is defined olehsinar rainbow, we will see the light reflected /
refracted sunlight. Referring to the drawings, we see that the rainbow ray for
red light at an angle of 42 degrees between the direction of incident sunlight
and the line of sight. Therefore, during the rain seen along the line of sight
that makes this angle with the direction of incident light, we will look
brighter. Thus rainbow-degree radius circle, centered at the corner of 42
antisolar point, as shown in the schematic here.
We do not see a full circle because the earth gets in the
way. The lower the sun is the horizon, over-the circle that we see right at
sunset, we'll see a rainbow full of half-circle with the top of the arch 42
degrees above the horizon. The higher the sun in the sky, the smaller arches of
the rainbow on the horizon.

The first explain the origin of the rainbow with
proper is Mr rene descartes , a
scientist france . mr descartes explain , the rainbow is a miracle the sun and
a grain water in the air . opinion mr descartes about rainbow quoted until now
. hmm , may be said , mr rene descartes is bapaknya the rainbow .
ü
Origin of the Rainbow
Rainbows only occur if there is sunlight and rain. Shhh, know
baseball, it actually rain drops spherical, lo. ukurang rainwater is very small
ball. Grain rainwater clear as glass. The human eye sees ray of white light
mataharisebagai. The white color is actually a combination of sunlight berbagas
color. Well, the magic happens when the light bulb rainwater to penetrate the
grain. through the water when it rains, the sun rays broke in
me-ji-ku-hi-bi-ni-u. The result, you see a rainbow when the sun shines on a
rainy day.
ü
Beautiful rainbow
The drops of rain there is a small spherical and large balls.
Large grain rain to 2 millimeters in size. Grain size of 0.01 millimeters of
rain. Colors of the rainbow will appear full and good if the sun on the large
grain rain. Small grains of water produces a rainbow of colors that overlap and
pale.
ü
Rainbow Morning Afternoon
Rain rainbow only appears in the pie or a sunny afternoon.
rainbow arc length also appear if rain occurs in the morning and afternoon.
Rainbow will not appear despite the rain and the sun shines bright at 12 noon.
Because, the sun is above our heads at 12 noon. Rainbow appears when the sun is
behind us.
ü
Under the light of the Rainbow
Under the arc of the rainbow, the sky always looks bright.
Because, the light color of the rainbow warmi back to being a white color in
the rainbow arc bwah.
ü
Full Moon Rainbow
This rainbow can appear at night during full moon and the
rain. Moonlight can penetrate the water beads and become a rainbow.
Unfortunately, a rainbow full moon looked pale and thin.
ü
Rainbow Space
Rainbow is not only happening on Planet Earth. NASA
scientists also suspect rainbow occur on Titan. Titan is a moon around Saturn.
location of the moon Titan is very far from the sun. Rainbows on Titan appear
pale because the sun is dim in the Titan.
ü
Another question about Rainbow
Humphreys
(Physics of Water, p 478) discusses some of the "popular" questions
about the rainbow:
·
"What is the distance of the rainbow?"
It is near or far, according to which the drops of rain, stretching from
closest to farthest illuminated drops along the elements of the rainbow cone.
·
Why are rainbows so often seen during the summer
and so seldom during winter "To see the rainbow?, People have to have rain
and sunshine. In winter, the water droplets freeze into ice particles that do
not produce a rainbow but scatter light in the other pattern very interesting.
·
"Why are rainbows so rarely seen in
daylight?" Remember that the rainbow is the center of the circle opposite
the sun so it is as far below the level of the observer when the sun is above
it.
·
"Do two people ever see the same
rainbow?" Humphreys points out that "because the rainbow is a special
distribution of colors (produced in a certain way) with reference to a certain
point - eye of the observer - and as no single distribution can be equal to two
separate points, so that two observers do not, and can not, see The same
rainbow. "In fact, each eye sees its own rainbow! Of course, the lens of
the camera will record images of the rainbow that can then be seen my many
people! (Thanks to Tom and Rachel Ludovise for this show!)
·
"Can the same rainbow will be seen by
reflection, as seen in person?" On the basis of arguments given in the
previous question, bows appropriate for two different points which are produced
by different drops, hence, the bow seen by reflection is similar to that seen
immediately ".
Ø The formation of rainbow
Let us look when
sunlight paradoxirus mirror right angled or edge of a glass prism , or surface
froth soap , we see various colors in light . what happens is white light
refracted into various other wavelengths of light seen by our eyes as red , an
orange , yellow , green , blue , and purple . other wavelengths of light form
ribbon parallel lines , each color it with color next to him . this is called
spektrum ribbon . in the spectrum , that red line will always be on one end and
biri and purple at the other side , and this is determined by the divergence
wavelength .
When we see a rainbow,
just the same as when we look at the spectrum. In fact, the Rainbow is curved
spketrum caused by the refraction of sunlight. When sunlight passes through
water droplets, it membias like when passed through a prism of glass. So in the
droplets of water, we've got different color extends from one side to the other
water droplets. Some of the colored light is then reflected from the far side
in the water droplets, back and out of the water droplets. Lights out back of
droplets of water towards a different, depending on the color. And when we see
these colors in the Rainbow, we will see it with red in most established top
and purple at the very bottom of the Rainbow.
Rainbow can only be
seen at rain along with the sun shines , but the side opposite to the observer
. are we have to be among the sun and droplets of water with the sun dibekalang
us . the sun , our eyes and the center of the bow rainbow should be in a
straight line .
A collection of colors
that are expressed in wavelength (usually denoted by λ) is called the color
spectrum. These colors are the components of white light called visible light
(visible light) or waves appear. Other components are not visible light
(invisible light), such as infrared (on the right in red) and ultraviolet (on
the left orange). White light that we usually see (also called visible light or
visible light) consisting of all components of the colors in the spectrum above
- of course there are other components that are not visible, so-called
invisible light.
The simplest tools are
often used to describe the color white is a glass prism. A glass prisms
decompose white light that comes into the light components. In nature is not
only able to decipher the prism of light. In addition. water droplets of rain
water is one example of the available objects in nature that could decompose
white light. When a beam of white light on a drop of water, these water
droplets act like prisms. He describes the white light was so created the
colors of the rainbow. A drop of water act like a prism when it receives a beam
of white light. The light is partially reflected toward the observer, partly
transmitted. The color of the rainbow as the width of the blocks because we
only see one color to the water droplets. Sunlight by water droplets A
described only up to our eyes at red wavelengths. Meanwhile, the water droplets
B gives purple color wavelengths. Droplets of water on them to give each one wavelength
in our eyes. So in the end the viewer to see a full rainbow of colors.
We can only see a
maximum of half circle rainbow. To see a full rainbow circle, then we must
stand on higher ground.
The illustration on the
image above shows that the circular rainbow. It is true that a circular
rainbow, not a satellite dish as some people. On the ground, we only see a
maximum of half circle rainbow. If we stand on the rain, for example on an
airplane, then we can see a rainbow complete circle. This is all due to the
optical geometry of the decomposition process colors. With this optical
geometry we also could explain the straight line that passes through our eyes
and the sun also passes through the center of the circle of the rainbow.
Because the rainbow is created involving a distance of the observer with water
droplets, then the rainbow is always moved with the movement of the observer.
This makes us a rainbow constant distance (equal), in other words we could
never approach the rainbow.
Rainbows are formed due
to refraction of sunlight by water droplets in the atmosphere. When sunlight
through water droplets, the light is bent in such a way that makes the colors
that exist in a separate light. Each color is deflected at different angles,
and the color red is the color most recent is bent, while purple is the most
first.
Great Dictionary of the
rainbow by Indon Esia Language is the arch in the sky the color spectrum as a
result of the refraction of sunlight by rain or dew point. All colors of the
rainbow produced by sunlight begins. The sun itself has multiple colors called
polychromatic. Light can be captured clearly by the human eye there are only
seven colors: red, orange, yellow, green, blue, indigo, and violet
(mejikuhibiniu). Now the seventh light is what is known as visible light.
Ever have someone ask,
why the color red is always located above the purple while lying under the
rainbow? Apparently, this is because the red light, the rainbow is a spectrum
of light that has the longest wavelength or lowest frequency rather than have
the other light in a rainbow spectrum. So that the red color of the rainbow is
always on top and the opposite color of purple is always at the bottom of this
is because the wavelength of violet light is low or has the highest frequency.
The uniqueness of the
rainbow is only visible shortly after the rain and sunshine accompanied,
usually occurs in the morning or late afternoon when the angle between the sun
and the earth is still low. It also determines the position of the observer, ie
if between rain and sunshine, and the sun is behind the observer. Resulting in
a straight line between sun, observer, and the arc of the rainbow.
Terbentuklahpelangi result of the refraction and observer positions earlier.
Rainbows are formed due
to refraction of sunlight by water droplets in the atmosphere. When sunlight
through water droplets, the light is bent in such a way that makes the colors
that exist in a separate light. Each color is deflected at different angles,
and the color red is the color most recent is bent, while purple is the most
first.
Originated from
sunlight, sunlight is the light that consists of several colors or often called
polychromatic. Light that can be captured by the human eye without the tools
with just seven colors: red, orange, yellow, indigo, and violet. These colors
are also called visible light.
In physics that has
been described by my teacher, including visible light electromagnetic waves are
the result of magnetic field and electric field. Wavelength of visible light
varies from 4000 Å to 7000 Å and also has a frequency of 4.3 x 7.5 x 1014 Hz to
1014 Hz.
In light of red and
purple why there are always above and below the rainbow?
This is because red
light is part of the visible light spectrum that has the lowest frequency or
the longest wavelength of visible light when compared to the other. And violet
light has the highest frequencies and shortest wavelengths. So that between red
and purple are not met, the red color in the end of the rainbow and the color
purple on the bottom of the rainbow.
Rainbow refraction
occurs when light experience when exposed to sun light rain. Rainbow can only
be seen when there is rain accompanied with sunlight. Also determine the
position of the observer, ie between rain and sunshine, and the sun is behind
the observer. Resulting in a straight line between sun, observer, and the arc
of the rainbow. As a result, forming a rainbow of refraction and the results of
earlier observers position.
The sunlight is
polychromatic light (made up of many colors). In white light is actually a
composite of various wavelengths of light with different. The human eye can
perceive at least seven colors are contained in sunlight, which will look at
the rainbow: red, orange, yellow, green, blue, indigo, and violet.
These wavelengths of
light to form ribbons parallel stripes, each color shades of the color next to
it. The tape is called a spectrum. In the spectrum, the red line has always
been on one side and blue and purple on the other side, and this is determined
by the difference in wavelength.
Rainbow spectrum is
nothing but a big arc that occurs due to refraction of sunlight by the drops.
When the sunshine through water droplets, such as when it refracts through a
prism of glass. So in the droplets of water, we've got a different color
extends from one side to the other water droplets. Some of the colored light is
then reflected from the far side of the water droplets, again and again out of
the water droplets.
Light back out of the
water droplets in different directions, depending on color. The colors of the
rainbow is made with red on top and purple on the bottom of the rainbow.
Rainbow can only be
seen when it rains in conjunction with the sun shining, but from the opposite
side to the viewer. The position of the observer must be between the sun and
water drops with the sun dibekalang person. The sun, the eye of the observer
and the center of the arc of the rainbow should be in a straight line.
This phenomenon usually
occurs when the air is very hot but rain drizzle. We can clearly see this
phenomenon, if we stand back to the sun. Rainbow can also be formed due to
foggy or dewy air.
In physics, a rainbow
can be explained as a natural refraction of events. Refraction is the process
diuraikannya one specific color into another color (also called the color
spectrum), through a medium / medium well specified.
In the rainbow, the
color berurainya occurs when white sunlight breaks down into a spectrum of
colors through the medium of rainwater. The spectrum of colors that occur
consist of red, orange, yellow, green, blue, indigo, and violet.
The most amazing
rainbow phenomenon will occur when the air a bit overcast and there was light
rain. When my back to the sun, we will look at the rainbow with clouds
background, the colors will look clear and unequivocal.
Rainbow phenomenon can
also occur around the waterfall. Water splashing around a waterfall into the
media to describe the color of sunlight that shines. Some cultures in the world
mentions the phenomenon of the rainbow as certain myths. In Greek myth known
that the rainbow is the path to heaven of the world through which God the
Revealer, Iris Gods.
Chinese mythology says
that the rainbow is an incision made by the Goddess Nuwa using stone in five colors.
While the mythology of India is known that the rainbow is the bow of Rama as a
reincarnation of Vishnu.
The sunlight is
polychromatic light (made up of many colors). In white light is actually a
composite of various wavelengths of light with different. The human eye can
perceive at least seven colors are contained in sunlight, which will look at
the rainbow: red, orange, yellow, green, blue, indigo, and violet.
These wavelengths of
light to form ribbons parallel stripes, each color shades of the color next to
it. The tape is called a spectrum. In the spectrum, the red line has always
been on one side and blue and purple on the other side, and this is determined
by the difference in wavelength.
Rainbow spectrum is
nothing but a big arc that occurs due to refraction of sunlight by the drops.
When the sunshine through water droplets, such as when it refracts through a
prism of glass. So in the droplets of water, we've got a different color
extends from one side to the other water droplets. Some of the colored light is
then reflected from the far side of the water droplets, again and again out of
the water droplets. Light back out of the water droplets in different
directions, depending on color. The colors of the rainbow is made with red on
top and purple on the bottom of the rainbow
Rainbow can only be
seen when it rains in conjunction with the sun shining, but from the opposite
side to the viewer. The position of the observer must be between the sun and
water drops with the sun dibekalang person. The sun, the eye of the observer
and the center of the arc of the rainbow should be in a straight line
What happens is that
white light is refracted into different wavelengths of light invisible to our
eyes as red, orange, yellow, green, blue, and purple. These wavelengths of
light to form ribbons parallel stripes, each color shades of the color next to
it. The tape is called "spectrum". In the spectrum, the red line is
always at one end and sheep as well as purple on the other, and this is
determined by the difference in wavelength. When we see a rainbow, the same as
when we look at the spectrum. In fact, the rainbow is a large curved spketrum
caused by refraction of sunlight.
When the sunshine
through the water droplet, it refracts through a prism such as glass. So in the
droplets of water, we've got a different color extends from one side to the
other water droplets. Some of the colored light is then reflected from the far
side of the water droplets, again and again out of the water droplets. Light
out of the water droplets back towards a different, depending on color. And
when we see these colors in the rainbow, we will see it is composed with a red
top and purple on the bottom of the rainbow. Rainbow can only be seen when it
rains in conjunction with the sun shining, but from the opposite side to the
viewer. The position we have is between the sun and the water droplets with
dibekalang our sun. The sun, our eyes and the center of the arc of the rainbow
shall be in a straight line.
The rainbow is
refraction of light. When it is refracted, the light will change direction.
Usually this occurs when the deflection of light moving from one medium to
another. This happens because light travels at different speeds in different
mediums.
When it enters a glass
prism, the light will be deflected. Similarly, if out of the prism.
In addition to refract
light, a prism separates white light into its component colors. Different
colors of light are different frequency bands, so it has a different travel
speed when entering a substance.
Low velocity of light
in the glass will be deflected more sharply when moving from air to glass,
because of differences in different speed. Not surprisingly, the components
that make up white light are separated by the frequency as it passes through
the glass. In the prism, the light is deflected twice, when in and out, so the
spread of the light occurs.
Can raindrops refract
and scatter light like a prism. In the right conditions, this refraction forms
rainbows.
Rainbow has a variety
of types. Surely any kind of symptoms of different nature. The following are
the types of the rainbow.
Double rainbow
(supernumerary rainbows). Double rainbow phenomenon referred to as a rainbow or
overlap can be considered as a rainbow in the rainbow. In the rainbow phenomenon
of this type, there are other spectra in the deepest part, the deeper the color
spectrum of the pale; or it can be said with a spectrum of pastel colors. This
phenomenon is very rare in nature. Based on the science of physics, explained
that the phenomenon of the rainbow in the rainbow are the result of
interference color or color combination. There is constructive interference
thereby providing a powerful spectrum. There is also destructive, resulting in
a weaker spectrum (pastel colors). Because of the interference, there was a
rainbow at the end of the rainbow, the colors inside the pale.
Reflected rainbow,
rainbow reflection. Rainbow that bounced and reflected (Reflected rainbow,
rainbow reflection). From its name we can say that the rainbow that bounced and
reflected rainbow is composed of two phenomena. There are times when rainbows
occur above the water, like rivers or lakes. When there is a phenomenon, the
surface of the water acting as a mirror, giving rise to the rainbow that
bounced and reflected. Phenomenon can be explained as follows. The sunlight is
deflected by water droplets, rain, and then reflected away from the water
surface. As a result there will be a rainbow that bounced below the horizon.
Although it is difficult to observe, at least a bounce rainbow will appear in
part only. That is, if the water is quite calm no ripples.
While the phenomenon of
reflected rainbow occurs when sunlight is reflected away from the surface of
the water, before it reaches the water droplets of rain. Usually this happens
on the surface of rainbow water which is quite spacious and quiet, and close to
the flow of rain water droplets.
Circumhorizontal arc.
Forming a circular rainbow arch horizontal (Circumhorizontal arc) type that
forms the arch of the rainbow in the cloud horizontal circular mengkristalnya
actually a symptom of the ice grains. So, kind of a rainbow is not even a
phenomenon of the rainbow. Natural phenomena like the rainbow is called a halo.
Rainbows on Titan
(Rainbows on Titan) of Saturn has the largest-sized satellite called the Titan.
Because Titan has a surface is wet and damp, rainbow phenomenon can occur on
the surface of Saturn's satellites are
Rainbow in the Sun Halo
sun is a circle rainbow around the sun. Halo can also occur around the moon at
night (partial lunar eclipse). Halo phenomenon is due to the refraction of
sunlight by water vapor in the atmosphere so it looks like a rainbow. Rainbow
arches often seen at the bottom of the horizon due to water vapor particles
deflect sunlight gathered in the lower atmosphere. On the other hand, in the
morning or late afternoon sun was still at a low angle. In the tilted position,
the ability to refract light water particles is greater, so the colors that
appear are also more complete. In the daytime, when the sun is perpendicular to
the Earth, the ability to be low so that the deflection of light color that
looks very limited. The color is too dark because of the view toward the Sun is
also hindered the dust. If in the morning, when the air is still clean, which
is redness appears. Not surprisingly, this halo phenomenon is also seen only
during the day, at around 12.00-1300. In addition, just like a rainbow, halo
phenomenon also can be seen only during the rainy season. After the rainy
season ends, usually no more halo or rainbow. You see, in the atmosphere is no
more water vapor.
Ø The formation of rainbow”s
colour
You see a
rainbow of colors made up my me-ji-ni-hi-bi-u (red, orange, yellow, green,
indigo, and violet) representing the composition of the colors are beautiful.
However, the colors are not formed for granted. Then how the colors of the
rainbow is created?
Light
coming from the sun is a combination of all colors, but we are the light of
ordinary white. But when the sun on the mirror or the edge of right-angled
glass prism, or a soap bubble surface, we see different colors in the light.
What happens is that white light is refracted into different wavelengths of
light invisible to our eyes as red, orange, yellow, green, blue, indigo and violet.
These
wavelengths of light to form ribbons parallel stripes, each color shades of the
color next to it. The tape is called a spectrum. In the spectrum, the red line
is always at one end and sheep as well as purple on the other, and this is
determined by the difference in wavelength. When we see a rainbow, the same as
when we look at the spectrum. In fact, the rainbow is a large curved spketrum
caused by refraction of sunlight.
When
sunlight through water droplets, such as when it refracts through a prism of
glass. So in the droplets of water, we've got a different color extends from
one side to the other water droplets. Some of the colored light is then
reflected from the far side of the water droplets, again and again out of the
water droplets.
Light out
towards the back of the water droplets that vary depending on the color. When
you see these colors in the rainbow, you see it is composed of a red top and
purple on the bottom of the rainbow.
Rainbow can
only be seen when it rains in conjunction with the sun shining. But from the
opposite side with those who see. You must be between the sun and water drops
with the sun dibekalang you. The sun, your eyes and the center of the arc of
the rainbow shall be in a straight line.
Rainbow is
the only electromagnetic waves we can see. It consists of a spectrum of colors.
My friends could say what are the colors we can see in the rainbow? Among the
colors are: red, yellow, green, blue, orange, purple
And in fact
there are other colors that we can not refer directly to the eye. The red color
has the largest wavelength, while violet has the smallest wavelength. How do
rainbows form? Let us observe when the sunlight on the mirror or the edge of
right-angled glass prism, or a soap bubble surface, we see different colors in
the light.
What
happens is that white light is refracted into different wavelengths of light
invisible to our eyes as red, orange, yellow, green, blue, and purple. These
wavelengths of light to form ribbons parallel stripes, each color shades of the
color next to it. The tape is called "spectrum". In the spectrum, the
red line is always at one end and sheep as well as purple on the other, and
this is determined by the difference in wavelength. When we see a rainbow, the
same as when we look at the spectrum. In fact, the rainbow is a large curved
spketrum caused by refraction of sunlight.
When the
sun's light through water droplets, such as when it refracts through a prism of
glass. So in the droplets of water, we've got a different color extends from one
side to the other water droplets. Some of the colored light is then reflected
from the far side of the water droplets, again and again out of the water
droplets. Light out of the water droplets back towards a different, depending
on color. And when we see these colors in the rainbow, we will see it is
composed with a red top and purple on the bottom of the rainbow. Rainbow can
only be seen when it rains in conjunction with the sun shining, but from the
opposite side to the viewer. The position we have is between the sun and the
water droplets with dibekalang our sun. The sun, our eyes and the center of the
arc of the rainbow shall be in a straight line.
Ø 7 Colour of Rainbow
Rainbow,
symbol of beauty that often manifest themselves after the rain and heat to
blend. As we know, the rainbow has seven colors are always a kompositor typical
in every appearance.
7 colors of
the spectrum will produce white when rotated. Apparently, the seven colors of
the rainbow is made up of Red Orange Yellow Green Blue Indigo Purple has a
meaning in each and tiapnya. What are the meaning of the seven colors of the
rainbow?
Meaning of 7 Rainbow Colors
· Red: The

luxury, aristocratic. Which is full of accessories and supplies.
Meaning of the Seven Color Rainbow For Life
Energy Light and Color
As human beings living in
the world, we received our first rays of the sun, which gives warmth, growth,
strength and more. Rays are accustomed we have learned, can be separated into
various kinds of light.
Apparently we will accept
and emotionally respond to existing light. In one study, * with similar shaped
light beam caused by the cloudy in the morning or a bright day, it affects our
emotions. Kekurnagn sunlight will also make us so bad mood, depression, and
feel less powerful.
Seven colors of the rainbow
that is helping us strengthen our spiritual power. Not only do they vibrate at
the earth's surface at the time of spreading, but it shook all the seven colors
of nature with the energy that never stops. These vibrant colors will create a
force with the function and purpose of each.
Ø Reason why rainbow’s shape
curved
You
know, why the form of rainbow curved? Why the shape is not round / square or
other shape? Let us review the formation of a little challenge that beautiful
rainbow. Rainbow is one of the beautiful scenery that we rarely see. If seen,
the shape of a rainbow as a bow in the sky appear blue due to refraction of the
sun when the rain is approximately where it can be seen the rainbow? Usually a
rainbow can be seen in the mountains or when cloudy or when the new rains
stopped falling or could we see a waterfall.
Rainbow is the only electromagnetic
waves we can see. It consists of a spectrum of colors. Are you able to say what
are the colors we can see in the rainbow? and in fact there are other colors
that we can not refer directly to the eye. The red color has the largest
wavelength, while violet has the smallest wavelength. How do rainbows form? Let
us observe when the sunlight on the mirror or the edge of right-angled glass
prism, or a soap bubble surface,
we see different colors in the light.
What
happens is that white light is refracted into different wavelengths of light
invisible to our eyes as red, orange, yellow, green, blue, and purple. These
wavelengths of light to form ribbons parallel stripes, each color shades of the
color next to it. The tape is called "spectrum". In the spectrum, the
red line is always at one end and blue and purple on the other, and this is
determined by the difference in wavelength. When we see a rainbow, the same as
when we look at the spectrum. In fact, the rainbow is a large curved spectrum
caused by the refraction of sunlight.
It
turned out to see the beautiful rainbow that there are a variety of conditions.
The first requirement is that we have turned a light source at the sight of a
rainbow. In this case, the light source in question is the sun. The second
condition is the cause why a rainbow arched rainbow that we have to look at
from an angle of about 40 degrees apart from this point of the rainbow will not
look well. Therefore, a rainbow arched across the sky look spacious. So in
other words the curved shape of the rainbow was not solely because he created
the curve. However, because our field corner and the ability of our eyes is
what makes it look curved shape.
Ø Type of rainbow
J Classic Rainbows
Nature consists of six rainbow colors: red, orange, yellow,
green, blue and purple. The intensity of each color may be due to various
atmospheric conditions and the time (later).
Most everyone has seen a classic, garden-variety rainbow –
sometimes in their gardens while watering their plants with a misting spray.
Natural rainbows are made up of 6 colors: red, orange,
yellow, green, blue and violet. The intensity of each color may vary due to
atmospheric conditions and the time of day (more on that later).
J Circular Rainbows
Rainbow it really looks like a perfect arc of a circle (with
radius exactly 42 degrees, according to Descartes), although it is difficult to
see the rainbow because the soil has a habit of blocking.
The rainbows most of see are actually arcs of perfect circles
(with radii of exactly 42 degrees, according to Descartes), though viewing a
complete rainbow is difficult as the ground has a habit of getting in the way.
The advent of powered flight and aerial photography has
enabled the magnificence of circular rainbows to be revealed to an awestruck
public. Of course, if an airplane isn’t available a really high mountain will
do.
J Secondary Rainbows
Light can be reflected more than once inside a raindrop. Rays escaping after two reflections make a secondary bow.
The secondary has a radius of 51º and lies some 9º outside the primary bow. It is broader, 1.8X the width of the primary, and its colours are reversed so that the reds of the two bows always face one another. The secondary has 43% of the total brightness of the primary but its surface brightness is lower than that because its light is spread over its greater angular extent. The primary and secondary are are concentric, sharing the antisolar point for a center.
Primary rainbows are often accompanied by secondary rainbows
that are usually thinner and dimmer than the main rainbow. Here’s a bit of
trivia that may come in handy at parties or around the water cooler: the area
between primary and secondary rainbows that appears darker than the surrounding
sky is called “Alexander’s Band”.
Secondary rainbows are remarkable for one particular
characteristic: they display the spectrum in reverse order from that of a primary
rainbow. It’s not something most people are familiar with, as is seen in the
photoshop rendering above. Though sketched from the artist’s memory of an
actual event, the repeated structure of both rainbows shows that it’s not an
accurate portrayal.
J Red Rainbows
Sunset
and sunrise rays travel long
paths through the lower atmosphere where they are scattered
by air molecules and dust. Short wavelength blues and greens are scattered most
strongly leaving the remaining transmitted light proportionately richer in reds
and yellows. The result, glorious
sunsets and red rainbows
Red
Rainbows are usually visible at dawn or dusk when the thickness of the Earth's
atmosphere into the blue filter, leaving more red or orange droplets reflect
and refract light water. The result is a rainbow with red end of the spectrum
is greatly increased.
J Sundogs
A sun dog or sundog, scientific name parhelion (plural parhelia) from Greek παρήλιον (parēlion), meaning
"beside the sun"; from παρά
(para), meaning "beside", and ἥλιος
(helios), meaning "sun", also called a mock sun or a phantom sun, is an atmospheric phenomenon that creates bright spots of light in
the sky, often on a luminous ring or halo on
either side of the sun.
Most
often seen in the heavens on the day low wintery bright , sundogs made when the
sun shines through ice crystals high in the atmosphere . sundogs ruby colored
on the inside and purple on the outside with the rest of the spectrum of
crowded in betwixt . growing thick concentration ice crystals in the air ,
growing thick again its structure .
Sundogs
may appear as a colored patch of light to the left or right of the sun, 22°
distant and at the same distance above the horizon as the sun, and in ice
halos. They can be seen anywhere in the world during any season, but they are
not
Always
obvious or bright. Sundogs are best seen and are most conspicuous when the sun
is low.
Sundogs
are not rainbows per se, but share many of their visible attributes. Most
commonly seen low in the sky on a bright winter’s day, sundogs are created when
sunlight shines through ice crystals high in the atmosphere. Sundogs are red on
the inside and violet on the outside with the rest of the spectrum crammed in
between. The thicker the concentration of ice crystals in the air, the more
defined the structure of a sundog and its associated arcs becomes.
Moonlight
can be acted on by ice crystals to form – you guessed it – “moondogs”. The
image above was taken in Antarctica where, due to frigid air temperatures and
blowing snow, sundogs and moondogs are extremely common.
J Fogbows
A fog bow is a similar phenomenon to a rainbow, however, as its name suggests, it appears as a bow
in fog rather than rain.
Because of the very small size of water droplets that cause fog—smaller
than 0.05 millimetres (0.0020 in)—the fog bow has only very weak colors, with
a red outer edge and bluish inner.
fogbows more rarely seen
than rainbow because certain parameters that must be adjusted to created them .
e g , a light source must be behind observer and earthiness . also , mist
behind the observer to be very thin so the sun can shine through a thick mist
in front .
In many cases when the
droplets are very small, fog bows appear white, and are therefore sometimes
called white rainbows.
This lack of color is a distinguishing feature from a glory, which has multiple pale
colored rings caused by diffraction. When the droplets forming it are almost
all of the same size the fog bow can have multiple inner rings, or supernumeraries,
that are more strongly colored than the main bow. According to NASA:
The fogbow's lack of colors
is caused by the smaller water drops ... so small that the wavelength of light becomes important. Diffraction smears out colors that would be
created by larger rainbow water drops ...[1]
A fog bow seen in clouds,
typically from an aircraft looking downwards, is called a cloud bow. Mariners sometimes call fog bows sea-dogs.
Fogbows are much rarer than
rainbows because certain narrow parameters must align to create them. For one,
the light source must be behind the observer and low to the ground. Also, any
fog to the rear of the observer must be very thin so that sunlight can shine
through to the thicker fog in front.
Many fogbows display paler
colors compared to rainbows and some are mainly white. This is due to the fog
being composed of exceedingly fine water droplets.
J Waterfall Rainbows
The fog a waterfall commingle into the flow of air constant
atmosphere continuous , regardless of the weather . it makes a photograph teman
air plunge are excellent for the rainbow ! selection couples some picture of
the most famous waterfall in unison by some amazing rainbow .
Waterfalls kick a constant stream of mist into the air and
the atmospheric saturation goes on constantly, regardless of the weather. This
makes waterfalls excellent photographic companions to rainbows! The above
selection of images pairs some of the world’s most famous waterfalls with some
equally stunning rainbows
A variation of waterfall rainbows are “spray bows”, formed on
sunny days when wind kicks up ocean or lake waves and the air becomes saturated
with mist and moisture.
J Fire Rainbows
Fire rainbows are not actually rainbows and have no
connection with fires. The true name for this exquisitely beautiful optical
effect is “circumhorizontal arc”.
The phenomenon can only be viewed under certain precise
conditions: the cirrus clouds that act as prisms must be at least 20,000 feet
high and the sun must strike them when it is at an elevation of 58 to 68
degrees. Fire rainbows are never seen at locations situated more than 55
degrees north or south.
Rainbow this is not made of fire , whose true name is to the
optical effects this beautiful is circumhorizontal arc . this phenomenon can
only be seen in specific specific conditions : a cirrus cloud , that acts like
a prism should at least be in the elevation of 20 . 1 000 legs and the sun shall
highlight when they were at the altitude degree . rainbow fire never seen in
the location of more than 55 degrees north or south .
J Moonbows
Moonbows, like moondogs, are the lunar counterpart to
rainbows. They’re also much more difficult to witness due to the requirement of
a passing rainstorm and, ideally, a bright full moon unblocked by clouds.
In the spectacular image above, the photographer used a
30-second exposure at 4:34am in the morning, the moon being nearly full. The
bright star under the moonbow is the orange supergiant Arcturus.
Moonbows , as moondogs , is a partner for the rainbow lunar .
they also much more difficult viewed as a storm with rain to be passed and ,
ideally , then the moon light not obstructed by clouds .
A moonbow (also known as a lunar rainbow, white rainbow,
lunar bow, or space rainbow) is a rainbow produced by light reflected off the
surface of the moon rather than from direct sunlight. Moonbows are relatively
faint, due to the smaller amount of light reflected from the surface of the
moon. They are always in the opposite part of the sky from the moon.
Because the light is usually too
faint to excite the cone color receptors in human eyes, it is difficult for the
human eye to discern colors in a moonbow. As a result, they often appear to be
white.However, the colors in a moonbow do appear in long exposure photographs.
Ø Unique fact about rainbow
Defined as the line
color of the rainbow is formed due to reflection and refraction of sunlight in
the rain.
One of the sightings of
the rainbow.
# 2 .We can see the
rainbow as the light is refracted when it passes from air medium medium rain.
The combined color light is white, but when it is refracted will be a variety
of colors. Thus approximately refraction scheme.
# 3 . If you see a
rainbow, you can bet most likely it was raining and the sun is behind you and
the rain in front so that the center of the arc of the rainbow is right across
/ opposite the sun. Although I think this picture hoax / engineering, this
figure could prove that a rainbow is formed due to rain.
# 4 . Although it looks
like a bow, the rainbow is actually a spherical form in full.
As this is the actual
form of the rainbow.

Come on, forget about a
child's fairy tale, because it is based on the fact the number 7, the rainbow
seemed to move away according to our distance when we were moving towards the
rainbow.
# 9. Actually, everyone sees the rainbow in
the perception of their own. So when you see the rainbow, the person next to
you will see the rainbow of light reflection of different rainwater. The color
of the rainbow can vary depending on how each person interprets their eyes.
# 10. Rainbow is very
good when viewed from the science of Feng Shui. Rainbow has a positive energy
that can calm the mind and have the power restructuring.
Ø Double rainbow
Sometimes we see two
rainbows at once, what causes this? We have followed the path of a ray of
sunlight as it enters and is reflected inside the raindrop. But not all of the
energy of the ray escapes the raindrop after it is reflected once. A part of
the ray is reflected again and travels along inside the drop to emerge from the
drop. The rainbow we normally see is called the primary rainbow and is produced
by one internal reflection; the secondary rainbow arises from two internal
reflections and the rays exit the drop at an angle of 50 degrees° rather than
the 42°degrees for the red primary bow. Blue light emerges at an even larger
angle of 53 degrees°. his effect produces a secondary rainbow that has its
colors reversed compared to the primary, as illustrated in the drawing ,
adapted from the Science Universe Series Sight, Light, and Color .

ü
The Irish leprechaun's secret hiding place for
his pot of gold is usually said to be at the end of the rainbow. This place is
impossible to reach, because the rainbow is an optical effect which depends on
the location of the viewer. When walking towards the end of a rainbow, it will
appear to "move" further away (two people who simultaneously observe
a rainbow at different locations will disagree about where a rainbow is).
ü
Another ancient portrayal of the rainbow is
given in the Epic of Gilgamesh: the rainbow is the "jewelled necklace of

paintings. Frequently these have a symbolic or programmatic significance (for
example, Albrecht Dürer's Melancholia I). In particular, the rainbow appears
regularly in religious art (for example, Joseph Anton Koch's Noah's
Thanksoffering). Romantic landscape painters such as Turner and Constable were
more concerned with recording fleeting effects of light (for example,
Constable's Salisbury Cathedral from the Meadows). Other notable examples
appear in work by Hans Memling, Caspar David Friedrich, and Peter Paul Rubens.

Rainbow flags tend to be used as a sign of a new era, of
hope, or of social change. Rainbow flags have been used in many places over the
centuries: in the German Peasants' War in the 16th century, as a symbol of the
Cooperative movement; as a symbol of peace, especially in Italy; to represent
the Tawantin Suyu, or Inca territory, mainly in Peru and Bolivia by some Druze
communities in the Middle east; by the Jewish Autonomous Oblast; to represent
the International Order of Rainbow for Girls since the early 1920s; and as a
symbol of gay pride and LGBT social movements since the 1970s.
CHAPTER III
CLOSING
A. CONCLUSION
A rainbow is an optical and
meteorological phenomenon that causes a spectrum of light to appear in the sky
when the Sun shines on to droplets of moisture in the Earth's atmosphere. It
takes the form of a single arc. Rainbows caused by sunlight always appear in
the section of sky directly opposite the sun.
The sky is the nature's
canvas on which she paints beautiful and ever changing pictures. Light itself
is her color and she uses it in various ways to create beautiful optical
phenomena. One such rare masterpiece of her creation is the fire rainbow. In
this article, I discuss some interesting fire rainbow facts and explore how
this phenomenon is created.
A rainbow spans a continuous
spectrum of colours; the distinct bands (including the number of bands) are an
artefact of human colour vision, and no banding of any type is seen in a
black-and-white photo of a rainbow (only a smooth gradation of intensity to a
maximum, then fading to a minimum at the other side of the arc). For colours
seen by a normal human eye, the most commonly cited and remembered sequence, in
English, is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet
(popularly memorized by mnemonics like Roy G. Biv). However, colour-blind
persons will see fewer colours.
The first explain the origin of the
rainbow with proper is Mr rene
descartes , a scientist france . mr descartes explain , the rainbow is a
miracle the sun and a grain water in the air . opinion mr descartes about
rainbow quoted until now . hmm , may be said , mr rene descartes is bapaknya
the rainbow .
Let us look when sunlight
paradoxirus mirror right angled or edge of a glass prism , or surface froth
soap , we see various colors in light . what happens is white light refracted
into various other wavelengths of light seen by our eyes as red , an orange ,
yellow , green , blue , and purple . other wavelengths of light form ribbon
parallel lines , each color it with color next to him . this is called spektrum
ribbon . in the spectrum , that red line will always be on one end and biri and
purple at the other side , and this is determined by the divergence wavelength
.
When we see a rainbow, just
the same as when we look at the spectrum. In fact, the Rainbow is curved
spketrum caused by the refraction of sunlight. When sunlight passes through
water droplets, it membias like when passed through a prism of glass. So in the
droplets of water, we've got different color extends from one side to the other
water droplets. Some of the colored light is then reflected from the far side
in the water droplets, back and out of the water droplets. Lights out back of
droplets of water towards a different, depending on the color. And when we see
these colors in the Rainbow, we will see it with red in most established top
and purple at the very bottom of the Rainbow.
Rainbow can only be seen at
rain along with the sun shines , but the side opposite to the observer . are we
have to be among the sun and droplets of water with the sun dibekalang us . the
sun , our eyes and the center of the bow rainbow should be in a straight line .
We can only see a maximum of
half circle rainbow. To see a full rainbow circle, then we must stand on higher
ground.
The illustration on the
image above shows that the circular rainbow. It is true that a circular
rainbow, not a satellite dish as some people. On the ground, we only see a
maximum of half circle rainbow. If we stand on the rain, for example on an
airplane, then we can see a rainbow complete circle. This is all due to the
optical geometry of the decomposition process colors. With this optical
geometry we also could explain the straight line that passes through our eyes
and the sun also passes through the center of the circle of the rainbow.
Because the rainbow is created involving a distance of the observer with water
droplets, then the rainbow is always moved with the movement of the observer.
This makes us a rainbow constant distance (equal), in other words we could
never approach the rainbow.
The rainbow is refraction of
light. When it is refracted, the light will change direction. Usually this
occurs when the deflection of light moving from one medium to another. This
happens because light travels at different speeds in different mediums.
Light coming from the sun is
a combination of all colors, but we are the light of ordinary white. But when
the sun on the mirror or the edge of right-angled glass prism, or a soap bubble
surface, we see different colors in the light. What happens is that white light
is refracted into different wavelengths of light invisible to our eyes as red,
orange, yellow, green, blue, indigo and violet.
Rainbow, symbol of beauty
that often manifest themselves after the rain and heat to blend. As we know,
the rainbow has seven colors are always a kompositor typical in every
appearance.
7 colors of the spectrum
will produce white when rotated. Apparently, the seven colors of the rainbow is
made up of Red Orange Yellow Green Blue Indigo Purple has a meaning in each.
Rainbow is the only
electromagnetic waves we can see. It consists of a spectrum of colors. Are you
able to say what are the colors we can see in the rainbow? and in fact there
are other colors that we can not refer directly to the eye. The red color has
the largest wavelength, while violet has the smallest wavelength. How do rainbows
form? Let us observe when the sunlight on the mirror or the edge of
right-angled glass prism, or a soap bubble surface, we see different colors in the light.
