Why does a rainbow appear when light goes through a prism?[edit]

White light has a combination of different colors. Such as red, orange, yellow, green, blue, indigo, and violet. All the colors have different wavelengths. When light moves through a prism, all the colors in the light go in all different directions. When they go in different directions, it becomes a rainbow. Here's what happens inside a prism: Violet have the shortest wavelength, so it moves downward. Indigo has the second shortest wavelength, so it moves a little more up than violet. Blue has a medium wavelength, so it moves a little more up than indigo. Green also has a medium wavelength, but it is a little bigger than blue. It moves more up than blue. Yellow has a big wavelength, so it moves higher up than green. Orange has a big wavelength, but bigger than yellow. It moves more up than yellow. And finally, red has the biggest wavelength. It moves the highest in the prism. That is what happens inside a prism. If you have a dreamcatcher that is made of glass, that is a prism. That's why you see rainbows up on your ceiling every morning. Do you have anything else that is a prism in your room? If you are not sure, ask your parents, they will tell you, I promise! If they aren't sure, go back on wiki, and I will tell you! — Preceding unsigned comment added by 68.9.245.187 (talk) 21:03, 13 March 2019 (UTC)

Even though the line is inside a comment tag, it messes with scripts trying to parse the document.
