If different colors of light had the same speed in matter, there would be no a. rainbows. When light is refracted there is a change In its a. frequency.
Lenses work because in different materials light has different a. wavelengths.
A fish outside water will see better if it has goggles that are a. tinted green-blue. Waves diffract most when their wavelengths are a. long. A hologram best illustrates a. resonance. Light 1c, 2b, 3c, 4b, Sa. An electron and a baseball move at the same speed.
