Light Fact Sheet Rainbow Colors


Light of Many Colors Experiment

Introduction: A prism or diffraction grating will disperse the light from a lamp into its many different colors. The sequence of colors is called a spectrum. Different lamps have different spectra because each lamp emits light uniquely based on its material and its temperature. One way to remember the colors of the rainbow is the name ROY G. BIV for the colors Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

Lamp Types: Tungsten lamps (normal light bulbs), fluorescent lamps (tube light bulbs), and arc lamps (neon, mercury, or other gas-filled lamps)

Procedure: View each different kind of lamp with a prism or diffraction grating. Use crayons or color markers to draw the spectrum as you see it.
