How do we know that different colors of light have different speeds in a material?
a. Because of measurements by Galileo of the speed of different colors of light. b. Because different colors reflect at different angles. c. Because the index of refraction depends on the speed of light in a material, and that index is different for different colors. d. Because Fizeau's measurements measured different colors of light to have different speeds. e. Because the colors combine to form white light.
