Rainbow facts

How are rainbows made?

Rainbows are a result of the sun's white light being broken up into it's component colors through the prism of a raindrop. This division of white light into its component colors is called Dispersion. The light is often double-reflected on either side of the raindrop before exiting and headed your way. The color of a light wave see depends on the frequency of the light wave entering your eyes.

This explains why we see the colors of a rainbow, but how come all the colors line up next to each other? Since different frequency light waves bounce and reflect differently meaning that the different colors line up coming at a slightly different angle from each other. (note: the frequency of a wave is the number of cycles of a wave to pass some point in one second. )
