Physics

2. a phenomenon in which two waves combine by adding their displacement together at every single point in space and time, to form a resultant wave of greater, lower, or the same amplitude.
3. a point along a standing wave where the wave has minimum amplitude.
6. the maximum value of upward displacement within a cycle
9. a decrease in the density of something. “a sound wave causes periodic rarefactions in its medium”
10. occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero.
11. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
13. The time it takes for two successive crests (one wavelength) to pass a specified point
14. a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium
15. a substance or material that carries the wave.
16. the distance between successive crests of a wave

1. a wave vibrating in the direction of propagation.
4. also known as a stationary wave, is a wave that oscillates in time but whose peak amplitude profile does not move in space.
5. the term frequency refers to the number of waves that pass a fixed point in unit time
7. a wave vibrating at right angles to the direction of its propagation.
8. a region of maximum amplitude situated between adjacent nodes in a vibrating body.
12. the minimum or lowest point in a cycle
