Waves

5. Time for a particle on a medium to make one complete vibration cycle
7. Change in direction of waves as they pass from one medium to another
8. maximum amount of displacement of a particle from its rest position
12. Waves bouncing off of barriers at the same angle as when they approach the barrier
13. Distance traveled by a given point in a given interval of time
14. Change in direction of waves
15. Two waves meeting
17. A change in direction of waves as they pass through an opening or around a barrier in their path
19. Transfered by a wave along a medium

1. Disturbance that travels through a medium
2. Effect produced by a moving source of waves
3. Point on a medium through which a longitudinal wave is traveling that has the maximum density
4. Point on medium where maximum positive displacement from rest occurs
6. Wave of increasing pressure
9. Substance or material that carries a wave
10. Point on medium where maximum negative displacement from rest occurs
11. Unit of frequency
12. A point on a medium through which a longitudinal wave is traveling that has the minimum density
16. Length of one complete wave cycle
18. How often particles of the medium vibrate
