Wave Unit Vocab

5. A unit of frequency (of change in state or cycle in a sound wave, alternating current, or other cyclical waveform) of one cycle per second.
6. Waves where the particle motion is in the same direction in which the wave is propagating.
11. The substance that carries a wave (or disturbance) from one location to another.
12. The highest surface part of a wave.
13. Wave that is an oscillation of matter, and therefore transfers energy through a medium.
15. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

1. Abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
2. The lowest part of a wave.
3. The ability to do work.
4. Motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
7. The rate at which something occurs or is repeated over a particular period of time or in a given sample.
8. Sound or other vibrations having an ultrasonic frequency, particularly as used in medical imaging.
9. The time it takes for two successive crests (one wavelength) to pass a specified point.
10. A wave's peak to peak or trough to trough.
14. The maximum extent of a vibration or oscillation, measured from the position of equilibrium.
