In this activity you will use a prism to see all the colors in white light. When you shine a light in just the right way on a prism, the light enters the prism, bends, and spreads out to show us all of the colors of the rainbow.
Rainbows work the same way.
When sunlight shines on raindrops in just the right way, the sunlight is bent as it moves through the drops. It spreads out and is reflected back to us as a colorful rainbow in the sky. Interactive Java Tutorial Refraction of Light Explore how light refracts as it moves from a vacuum to different mediums. The group of colors that we can see with a prism or in a rainbow is called the color spectrum. Each letter of the name is the first letter of a color.
