6. a point along a standing wave
9. the maximum displacement or distance moved by a point on a vibrating body or wave
10. a region in a longitudinal wave where the particles are closest together
11. point The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its
14. the opposite of a crest
16. a change in direction of waves when they bounce off a barrier
17. equals the distance between two successive wave crests or troughs.
19. vibrating in the direction of propagation.
20. can bend and move through the material

1. primarily depends on the amplitude of the sound wave
2. The distance between one peak of a wave to the next corresponding peak
3. transfer of energy from one location to another, especially through waves
4. vibrating at right angles
5. a phase in a sound wave
7. the time needed for one complete cycle of vibration to pass a given point.
8. The effects of a low wave
12. can bounce off the material
13. The sensation of a frequency
15. where the displacement of the medium is at a maximum
16. the negative displacement of one always coincides with the positive displacement of the other.
18. a boundary wave
