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.

ü 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.

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.

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.

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

The red color in the rainbow colors adapted for young blood with tempestuous passion. Red rainbow is also interpreted as a symbol of pure love.

· Orange: Emblem Health and Strength

Orange color of the rainbow appeared in the health welfare. Balance between health and strength. Also owned by the orange fruits and vegetables healthy carriers, such as carrots and pumpkins.

· Yellow : color defines the color of happiness, joy, and everlasting joy and a warm host.

· Green: Green Seal KesuburanWarna interpreted as a source of life. Green can also be interpreted as a symbol of hope and a sincere request.

· Purple: The symbol of Luxury

The color purple symbolizes as much greatness of a wise king. With a high level of 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 sunor 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.

# 5 . MeJiKuHiBiNiU

is an acronym commonly used to memorize the colors of Indonesia on the rainbow. While the west using the acronym

Roy. G. BIV

Red, Orange, Yellow, Green, Blue, Indigo, Violet.

# 6 . 7 colors of the rainbow in fact it is not only, but all the colors that exist in the world. But our eyes could not tell the difference. Various kinds of colors.

# 7 . Refraction angle of light to create rainbow is about 42 degrees to the observer's eye.

# 8. Have you ever heard the story when someone reaches the end of the rainbow are attached to the ground then it will find a box of gold there?

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 .

Ø Rainbow in culture

· Religious belief

ü The rainbow has a place in legend owing to its beauty and the historical difficulty in explaining the phenomenon.

ü In Greco-Roman mythology, the rainbow was considered to be a path made by a messenger (Iris) between Earth and Heaven.

ü In Chinese mythology, the rainbow was a slit in the sky sealed by goddess Nüwa using stones of five different colours.

ü In Hindu religion, the rainbow is called Indradhanush, meaning "the bow (Sanskrit and Hindi: dhanush is bow) of Indra, the god of lightning, thunder and rain". Another Indian mythology says the rainbow is the bow of Rama, the incarnation of Vishnu. It is called Rangdhonu in Bengali, dhonu (dhanush) meaning bow. Likewise, in mythology of Arabian Peninsula, the rainbow, called Qaus Quzaħ in Arabic, is the war bow of the god Quzaħ.

ü In Armenian mythology the rainbow is a belt of Tir, a Sun god.

ü In Norse Mythology, a rainbow called the Bifröst Bridge connects the realms of Ásgard and Midgard, homes of the gods and humans, respectively

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 the Great Mother Ishtar" that she lifts into the sky as a promise that she "will never forget these days of the great flood" that destroyed her children. (The Epic of Gilgamesh, Tablet Eleven)

ü The Church of Jesus Christ of Latter-Day Saints founder and prophet Joseph Smith stated that the second coming of the Christ would not occur in any year in which a rainbow is seen.

ü In the Dreamtime of Australian Aboriginal mythology, the rainbow snake is the deity governing water. In Amazonian cultures, rainbows have long been associated with malign spirits that cause harm, such as miscarriages and (especially) skin problems. In the Amuesha language of central Peru, certain diseases are called ayona’achartan, meaning "the rainbow hurt my skin". A tradition of closing one's mouth at the sight of a rainbow in order to avoid disease appears to pre-date the Incan empire.

ü In New Age and Hindu philosophy, the seven colours of the rainbow represent the seven chakras, from the first chakra (red) to the seventh chakra (violet)

· Art

Rainbows are generally described as very colourful and peaceful. The rainbow occurs often in 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.

· Music

In The Rainbow Connection, a song known for being sung by Kermit the Frog, the idea of a rainbow is seen as something to wish on, as it is popularly seen as a vision, or symbol of hope.

In End of the Rainbow by September, the singer sings about the rainbow, and how she will be at the end of the rainbow and her ex could see her there when he reaches the end of the rainbow.

End of the Rainbow is an award winning stage play with music (or musical drama) by Peter Quilter.

The group Rainbow and the song Rainbow Demon by Uriah Heep.

I Can Sing a Rainbow is a popular children's classic song written by Arthur Hamilton, despite the name of the song, not all the colours mentioned are actually colours of the rainbow.

Ronnie James Dio used rainbows as a thematic element in many of his songs, particularly as singer and lyrics-writer for Ritchie Blackmore's band Rainbow. Most notable among these are the songs Catch the Rainbow, Rainbow Eyes and the Dio song Rainbow in the Dark.

The band Radiohead released an album in 2007 named, In Rainbows.

The South Korean band Rainbow

Somewhere Over the Rainbow, a song sung by the character Dorothy Gale (Judy Garland) in the musical film The Wizard of Oz.

Japanese singer, Ayumi Hamasaki, has an album named RAINBOW with the same song name.

'Rainbow Country,' by Bob Marley.

Films

In A Shine of Rainbows, the young protagonist is promised to be taken into a rainbow.

In Marianne, a double rainbow was filmed by chance when Sandra is introduced for the first time.

In Rainbow, damage to a rainbow threatens the world at large.

In the film The Wizard of Oz, lead character Dorothy Gale sings the song "Over the Rainbow" where she fantasises about a place over the rainbow, where the world is in peace and harmony.

· Flags

Main article: Rainbow flag

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

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 .

We can only see a maximum of half circle rainbow. To see a full rainbow circle, then we must stand on higher ground.

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.
