1 Chapter 29 B Light Waves Thin Films

2 When light waves that are in phase meet, the result is a.brighter light. b.no light. c.dimmer light. d.light of shifted frequency.

3 When light waves that are in phase meet, the result is a.brighter light. b.no light. c.dimmer light. d.light of shifted frequency.

4 A beam of white light that reflects from a pair of closely spaced surfaces has color because some of the reflected light is a.converted to a different frequency. b.deflected. c.subtracted from the beam. d.amplified.

6 If a portion of a soap bubble in sunlight appears greenish blue, then the light canceled by interference was a.red. b.yellow. c.blue. d.greenish blue.

7 If a portion of a soap bubble in sunlight appears greenish blue, then the light canceled by interference was a.red. b.yellow. c.blue. d.greenish blue.

8 When light is canceled by the interference in thin films, the color produced is a.often brighter than the incident light. b.a primary color. c.the complement of the color canceled. d.iridescent.

9 When light is canceled by the interference in thin films, the color produced is a.often brighter than the incident light. b.a primary color. c.the complement of the color canceled. d.iridescent. Comment: Although iridescent colors are often seen when interference occurs in objects such as sea shells, the color always produced is the complement of the color canceled.
