Waves Vocab

3. lowest point of a transverse wave
5. material a mechanical wave moves through
7. Totally empty space (no medium). Sound cannot travel through this
9. type of wave where the medium moves perpendicular (vertical) to the direction the energy is moving.
13. type of wave where the medium moves parallel (horizontal) to the direction the energy is moving. Sound is this type of wave.
16. How many waves are created every second. Measured in Hertz (Hz)
17. When a wave changes direction because it goes into a new medium
18. maximum distance from the rest position that the medium moves in a wave

1. one wave hits another wave, their amplitudes combine and make a new wave
2. parts of a longitudinal wave that are closest together
4. transverse wave of pure energy that can go through both a medium and empty space (vacuum). Light is this kind of wave.
6. distance between two similar parts of a wave
8. a disturbance in matter that carries energy from one place to another
10. repeated back and forth or up and down motion that gives energy to a wave. Also called "oscillation"
11. When waves spread out to fill the space through which they are moving
12. disturbance that transfers energy from place to place
14. Highest point on a transverse wave
15. parts of a longitudinal wave that are spread apart
