Physics Review Question Unit: waves Year: 1991 Question#: 51 Question: Which is a characteristic of light produced by a monochromatic light source? (1 ) It can be dispersed by a prism. (2 ) It is a longitudinal wave. (3 ) Its frequency is constantly changing. (4 ) It can be polarized. What is this question really asking? Explanation by: Gabriel F [ Return to question menu ] Answer 1 A) It can be dispersed by a prism. INCORRECT This answer is wrong because monochromatic light cannot be dispersed into its component colors because it is only one color. return to top Answer 2 2)It is a longitudinal wave. All light is transverse waves, none are longitudinal waves. return to top Answer 3 3) Its frequency is constantly changing. INCORRECT Because monochromatic light does not switch colors so the frequency cannot change. return to top Answer 4 4)It can be polarized. CORRECT You can filter it out by its orientation. return to top What's this question really asking? What is true of monochromatic (one-color) light? return to top |
