Waves & Sound Energy

3. wave Wave that requires a medium through which to travel
4. Distance between two corresponding parts of a wave
5. Sound waves with frequencies above 20,000 Hz
6. Highest part of a transverse wave.
10. wave Wave that moves the medium in a direction perpendicular to the direction in which the wave travels
13. Small, tightly stretched, drumlike membrane in the ear.
16. A disturbance that transfers energy from place to place
17. The use of reflected sound waves to determine distances or to locate objects.
19. A repeated back-and-forth or up-and-down motion.
20. The part of a longitudinal wave where the particles of the medium are close together.
21. A point of zero amplitude on a standing wave

1. Maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium
2. Part of a longitudinal wave where the particles of the medium are far apart.
7. Bending of waves as they enter a new medium at an angle
8. wave Wave that appears to stand in one place.
9. The study of how sounds interact with each other and the environment
11. Combination of a longitudinal wave and a transverse wave that travels along the surface of a medium.
12. Number of complete waves that pass a given point in a certain amount of time
14. canal Narrow region leading from the outside of the human ear to the eardrum.
15. Unit used to compare the loudness of different sounds
18. Two folds of tissue that make up the human voice box
