Physics Definitions

3. a state/region of a minimum pressure in a medium transversed by compression.
5. wave a wave form that does not travel through space or along a string.
9. region in a longitudinal wave where the particles are closest together.
12. interference occurs when the maximum if two waves are at 180 degrees out of phase.
14. a point along a standing wave where the wave has minimum amplitude.
15. wave a wave which the particles of the medium wave move parallel to the propagation of the wave.

1. wave a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
2. the number of times per second that a sound pressure wave repeats itself.
4. interference two waves with the same frequency and amplitude.
6. a substance or material that can carry a wave.
7. relative strength of sound waves,which we percieve as volume or loudness.
8. the maximum value of upward displacement within a cycle.
10. the distance between successive nodes is equal to a half wavelength.
11. the size of a wave, measured from one peak to the next.
13. the lowest point below the rest position.
