Waves

3. the amount of time it takes one wavelength.
5. less dense regions in a compressional wave.
7. the bending of a wave caused by a change in its speed as it moves from one medium to another.
8. what waves move energy through.
10. alternating high points in a transverse wave.
11. a wave that is not purely transverse.
13. a type of wave that in the matter in the medium moves back and forth along the same direction.
16. distance between one point on a wave to another.
17. what moves through a medium.
19. a special type of wave pattern that forms when waves equal in wavelength and amplitude

1. energy transferred by a wave.
2. the process by which an object is made to vibrate by absorbing energy at its natural frequencies
4. when a object causes a wave to change direction and bend around it.
6. matter in the medium moves back and forth along the same direction the the wave travels.
9. a repeating disturbance or movement that transfers energy through matter or space.
12. low points in a wave.
14. a type of wave that are compressional.
15. the number of wavelengths.
18. when two or more waves overlap and combine to force a new wave.
