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. )

What is a radio wave?
Radio waves are the radiation and detection of a range of frequency of electromagnetic waves. Frequency is the number of wavelengths that pass a particular point in one second and for radio waves the frequency is from 3 kHz to 300 GHz. Radio waves like all electromagnetic waves are able to carry information through space. Radio waves can travel unimpeded through objects like buildings or people but light waves can not. This is because radio waves have a very long wavelength allowing them to pass through objects that have shorter wavelengths like you and me without problem. Reference:

How do we see in color?
The eye and nerves connected to the eye can visualize color by stimulation of colored cones within the retina from the different lightwave frequency that is projected by object. Reference:
