PRISM:

A prism separates white light into a group of seven colors called a spectrum. These seven colors are always in the same order. The colors of the spectrum are red, orange, yellow, green, blue, indigo, and violet. You can make up a name by using the first letter of each color to form a person's name. ROY G BIV Light can be reflected and bent. When light passes into the prism glass it slows down and it bends. The color red is not as bent the same way as the color violet is bent. When the colors come out of the prism, each color is bent in a different way and in a different quantity. People hang prisms from fancy lights in their homes or from windows that the sun shines through in their homes in order to fill their rooms with rainbows.

RAIN:

After it rains, there are lots and lots of water droplets in the air, around us. When the sun comes out, white light will strike all the drops of water. Each and every water drop of the millions and millions of water droplets acts just like a prism in that it separates the single strand of white light into seven colors. Sunlight enters each and every drop of water and the colors are given out as if the drop of water was a prism. This bending and reflecting happens at the same time in all the droplets of water and that is what forms the colors of the rainbow that you see after it rains.
