Waves

2. The bending of waves as they enter a different medium.
4. Sound hits it to vibrate the hammer.
6. The part of a longitudinal wave where the particles are close together.
10. How fast something is going
12. A disturbance that transfers that energy from place to place?
14. The bending of waves around a barrier.
15. The interference that occurs when two waves combine to make a larger one.
17. The amount of energy per second carried through a unit area by a wave.
18. Has the hammer, anvil, and stirrup.
20. A repeated back and forth or up and down motion
21. The ability of a material to bounce back after being disturbed.
22. Perception of intensity of a sound.

28. The distance between two corresponding points of a wave.
29. The number of complete waves that pass a given point in a certain amount of time.

1. Vibrations move the hairs which sends messages to the brain
3. A wave that moves the medium the medium in a direction perpendicular to the direction perpendicular to the direction in which the wave travels.
5. The apparent change in frequency of a sound as the source moves in relation to the listener.
7. A unit of measurement of loudness.
8. Directs sound to the ear canal.
9. The highest part of a transverse wave.
11. Material waves travel through
13. A wave that moves the medium parallel to the direction which the wave travels.
14. The interference that occurs when two waves combine two make a smaller one.
16. The part of a longitudinal wave where particles of the medium are far apart.
19. Perception of the intensity of a sound.
23. The lowest part of a transverse wave.
