Ch 15 P2 Test Review
Chapter 15 part 2 portion of huge test on 5/14/14
| Question | Answer |
|---|---|
| what is the amplitude of a transverse wave | the maximum distance the particles in a medium move from their rest position as the wave passes |
| what does a larger amplitude mean | there is more energy |
| what does the amplitude of a longitudinal wave depend on | the distance between particles in the compressions and rarefactions |
| what happens when the amplitude of a longitudinal wave increases | the particles in the medium get closer together in the compressions and farther apart in the rarefactions |
| what is wavelength | the distance between crest to crest or trough to trough |
| what is the frequency of a wave | the number of wavelengths that pass by a point each second |
| what SI unit is frequency measured in and what is its abbreviation | hertz (Hz) |
| what is the frequency of a wave (not wavelengths) | it is the same as the number of vibrations the vibrating object makes each second |
| what happens when the frequency of a wave increases | the length decreases |
