How much energy can the sun provide?
According to the American Solar Energy Society, enough sunlight falls on the earth's surface each minute to meet world energy demand for an entire year.

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. )
