Rainbow is one of the optical phenomenon that occurs naturally in the earth's atmosphere. In physics, the familiar colors of the identified wavelength. For example, the red color has a wavelength of about 625-740 nm, and blue around 435-500 nm.
Set of colors that are expressed in wavelengths is called the color spectrum. These colors are components of white light called visible light (visible light) or waves appear. The other component is light that is not visible (invisible light), such as infrared (on the right in red) and ultraviolet (left orange). White light that we usually see (also called visible light or visible light) consists of all the components of color in the spectrum above - of course there are other components that are not visible, so-called invisible light.
The simplest tool that is often used to describe the color white is a glass prism. A glass prism decompose white light that comes into components of light. In nature it is not only able to decipher the prism of light. Other than that. water droplets of rain water is just one example of the items available in nature which could decompose white light. When a beam of white light on a drop of water, these water droplets behave like a prism. He outlined earlier so that creates a white light colors of the rainbow. A drop of water behave like prisms when receiving a beam of white light. The light is partially reflected towards the observer, partly passed on. The color in the rainbow-like blocks wide because we only see one color for a drop of water. Sunlight outlined by water droplets A only up to our eyes in the red color wavelength. Meanwhile, the water droplets and provides a wavelength of violet. Droplets of which gives each of the wavelengths our eyes. So in the end the observer see a complete rainbow colors.
We could only see a maximum of a half circle rainbow. To see the full rainbow of the circle, then we must stand on higher ground.
The image above shows that a rainbow circle. It is true that the rainbow circle, not a parabola as some people. On the ground, we only see a maximum of a half circle rainbow. If we stand on the rain, for example, in aircraft, then we could see a rainbow a complete circle. This is all due to the optical geometry in the process of decomposition of color. With this optical geometry also we can explain the straight line that passes through our eyes and the sun also pass through the center point of a rainbow circle. Because of the distance involved observer rainbow created by water droplets, the rainbow always move to follow the movement of the observer. It makes our distance with rainbow constant (same ), in other words we could never approach the rainbow.
Rainbow formed by the refraction of sunlight by water droplets in the atmosphere. When sunlight through water droplets, the light is bent in such a way so as to make the colors that exist in the light separately. Each color deflected at different angles, and red is the color most recently bent, while purple is the most first.
originated from the sun, the sun is the light that consists of multiple colors or often called polychromatic. The light that can be captured by the human eye without tools only seven colors: red, orange, yellow, indigo, and violet. These colors also called visible light.
In the light of red and purple is why there is always above and below the rainbow?
This is because the red light is part of the visible light spectrum which has the lowest frequency or wavelength of the longest when compared with visible light. And violet light has the highest frequency and shortest wavelength. So between red and purple did not see each other, the red color is in the end of the rainbow and purple color at the very bottom in a rainbow.
Rainbow refraction occurs when light experiences when sunlight exposed to rain. Rainbow can only be seen when there is rain accompanied by sunlight. Also determines the position of the observer, ie between rain and sun, and the sun is behind the observer. Resulting in a straight line between the sun, the observer, and a rainbow.

Classic Rainbow
Natural rainbow is composed of the six colors: red, orange, yellow, green, blue and purple. The intensity of each color - masingnya different depending on atmospheric conditions and time.
Secondary Rainbows
This rainbow actually looks like the perfect arc of a circle ( with a radius of exactly 42 degrees, according to Descartes ).
Red Rainbows
Red Rainbows usually seen at dawn or dusk when the thickness of the earth's atmosphere filters blue, looks more like a trickle of red or orange light is reflected and refracted water. The result is a rainbow with red end of the spectrum.
Sundogs
The most commonly seen low in the sky on a sunny winter day, sundogs occurs when the sun shines through ice crystals high in the atmosphere. Sundogs are red on the inside and violet on the outside with the rest of the crowded spectrum in between. The thicker the concentration of ice crystals in the air, the thicker the structure.
Fogbows
The most commonly seen low in the sky on a sunny winter day, sundogs occurs when the sun shines through ice crystals high in the atmosphere. Sundogs are red on the inside and violet on the outside with the rest of the crowded spectrum in between. The thicker the concentration of ice crystals in the air, the thicker the structure.
Waterfall Rainbows
Waterfall mist mixed into the atmosphere constant air flow continuously, regardless of the weather. This makes a photograph a waterfall that is very good for rainbow.
Fire Rainbows
This rainbow is not made
of fire , the name for this beautiful optical effect is
"circumhorizontal arc". This phenomenon can only be seen under certain specific conditions : cirrus clouds, which act like prisms to be at least at an altitude of 20,000 feet and the sun should highlight when they are at an altitude of 58-68 degrees. Rainbow Fire was never seen at the site of more than 55 degrees north or south.
Moonbows
Moonbows is a partner for the lunar rainbow. They are also much more difficult to see because of a rain storm should pass and, ideally, a bright full moon is not blocked by clouds.
