Chapter 22 Reflection and Refraction of Light Quick Quizzes 1. (a). In part (a), you can see clear reflections of the headlights and the lights on the top of the truck. The reflection is specular. In part (b), although bright areas appear on the roadway in front of the headlights, the reflection is not as clear, and no separate reflection of the lights from the top of the truck is visible. The reflection in part (b) is mostly diffuse. 2. Beams 2 and 4 are reflected; beams 3 and 5 are refracted.

Unformatted text preview: 3. (b). When light goes from one material into one having a higher index of refraction, it refracts toward the normal line of the boundary between the two materials. If, as the light travels through the new material, the index of refraction continues to increase, the light ray will refract more and more toward the normal line. 4. (c). Both the wave speed and the wavelength decrease as the index of refraction increases. The frequency is unchanged. 233...
