WAVE UNIT

5. When one wave hits another wave, their amplitudes combine and make a new wave
9. The distance between two similar parts of a wave
10. a transverse wave of pure energy that can go through both a medium and empty space (vacuum). Light is this kind of wave.
13. The lowest point of a transverse wave
14. when waves spread out to fill the space through which they are moving
16. when a wave changes direction because it goes into a new medium
18. a wave that disturbance in matter that carries energy from one place to another
19. the material a mechanical wave moves through

1. the specific direction that a transverse wave is vibrating
2. how many waves are created every second. Measured in Hertz (Hz)
3. The parts of a longitudinal wave that are spread apart
4. The highest point on a transverse wave
6. A repeated back and forth or up and down motion that gives energy to a wave. Also called "oscillation"
7. a type of wave where the medium moves parallel (horizontal) to the direction the energy is moving. Sound is this type of wave.
8. A disturbance that transfers energy from place to place
11. The parts of a longitudinal wave that are closest together
12. The maximum distance from the rest position that the medium moves in a wave
15. a type of wave where the medium moves perpendicular (vertical) to the direction the energy is moving.
17. totally empty space (no medium). Sound cannot travel through this
