Rainbows are created by refraction and reflection of the sun’s rays in falling rain or mist. Sunlight strikes the front of the raindrop and is refracted separated into its colors. Then the light hit the back of the raindrop and is reflected, and is refracted again as it leaves the raindrop. What makes colors in the rainbow? The sunlight consists of all wavelengths of visible light, which we simply see as white because they are all combined together.

The color is constantly changing from red to violet. Each of the colors presents in white light are bent a different amount in passing through t...
