Sound Waves

2. a wave or periodic function is the distance over which the wave's shape repeats.
5. a measurement of the amount of energy transferred by a wave.
8. a point along a standing wave where the wave has minimum amplitude.
11. is the lowest point.
12. a wave that oscillates in time but whose peak amplitude profile does not move in space.
14. the spreading of waves as they pass through or around an obstacle.
15. when the speed of a wave depends on its frequency.
16. waves in which the direction of propagation aligns with the direction of vibration of the medium.
17. the material or empty space through which waves travel.

1. a part of a wave where the particles of a medium are spread apart, resulting in a low pressure area.
3. the transfer of energy from a wave to a medium.
4. the distance traveled by a given point on a wave in a given interval of time.
6. when a wave changes direction as it passes from one medium to another.
7. the number of waves that pass a point in a certain period of time.
9. a state of balance or no change over time
10. the highest point of a wave
12. a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
13. the amount of time it takes for a single wave cycle to complete
