Everyone has been familiar what rainbow is. But do you know how the process of it is? Rainbow is a natural phenomenon which occurs with a very interesting physics processes to be observed. So here will be described how the process of rainbow occurs. Rainbow is a big arc spectrum which occurs due to the reflection of sunlight by water grains. Rainbow is an optical and meteorological phenomenon in the form of multi-colored light that seems parallel to each other in the sky or other medium. Rainbow appears as an arc light with a tip leads to the horizon in a light rain. It can also be seen around a raging waterfall. Rainbow usually occurs when the air is very hot and the rain drops lightly. We can see the phenomenon clearly if we stand against the sunlight. Rainbow can also be formed by foggy air of frosted. In physics, a rainbow can be explained as a natural refraction event. Refraction is the process of decomposition of a specific color into another color (red: the color spectrum) through a specific media. The process of color decomposition occurs when the white sunlight breaks down into a spectrum of colors through rainwater. The spectrums of colors which occur consist of violet, red, indigo, blue, green, yellow, and orange.1.The first paragraph is called ....
