White light is composed of all the rainbow colors. You can break light down by using prisms.
What You'll Need:
- Scissors
- Cardboard
- Prism
- White paper
Cut a slit in a large piece of cardboard. Place the cardboard in a sunny window so that a shaft of sunlight shines through the slit. In one hand, hold a prism in front of the cardboard so that the sunlight passes through it. With your other hand, hold a sheet of white paper so that the light passing through the prism shines on it. You will see a rainbow of colors on the paper.
