The rainbow is an optical phenomenon that occurs when sunlight and rain react with each other in a certain way. The rainbow is formed because of the refracting sunlight.This light travels from one medium to another by droplets of water in the atmosphere.
The process of the occurrence of a rainbow is: When the sun hits the rain, the light changes direction (refracted) by the water granules in the air. The existence of differences in wavelengths and different angles when sunlight is refracted causes the colors in sunlight to spread and separate. Apparently, there is sunlight that bounces back or more precisely reflected. Well when the sun comes again through the water when it rains, the light is refracted again.
You also need to know that the rainbow can only be seen in the rain and there is sunlight. Your position as an observer also determines the tablet! You can see the rainbow if you are between the rain and the sun. The sunlight is behind the observer, a straight line with a rainbow bow or in other words you have to turn your back to the sun. Well because of the process of refraction, formed a rainbow in front of the eyes of the observer!
You can see the rainbow when bright sunlight, the rain or fog and the right sun corner conditions. As you know that the position of the observer must be back to the sun, or more precise if the angle reaches 42 o . Wow what would yaa think? The point of the rainbow is more likely to be seen before sunset or with the sun being lower than the sky guys! Hence the evening is a good time to see the rainbow, especially if it rains!
Well, then the colors of the rainbow how it can be formed like that ?
The answer is that these colors come from the sun (or so-called polychomatics) that have some color in the formation of a rainbow. Some visible light can be seen into 7 colors: red, orange, yellow, green, blue, indigo and purple. The color appears and is referred to as visible light. Visible light is the electromagnetic waves that arise due to the presence of electric fields and magnetic fields. The colors in the light have different wavelengths and frequencies so that it determines the color sequence in the rainbow guys.
You already know what the rainbow color order is? Why is red always at the beginning and purple always end?
Red light is part of the light that has the longest wavelength or in other words has the lowest frequency of other light. As for the color purple has the shortest wavelength or in other words has the highest frekuesni so red and purple will not meet but separated by other colors in sequence. Well the colors are formed sequentially in accordance with the frequency and wavelength of guys.
How guys? Already understand, how the process of the occurrence of a rainbow? It's a shame when you miss the rainbow phenomenon when it rains, hopefully you can often see the rainbow !
