To determine the amplitude of a wave, you would need to know the . A) distance from the crest to the trough. B) maximum displace
ment of the wave from the equilibrium position. C) number of cycles in a given period of time. D) the distance from the crest of one wave to the crest of the next wave.
B) Maximum displacement of the wave from the equilibrium position
Explanation:
The amplitude, a, of a wave is the distance from the center line to the top of a crest or to the base of a channel. Amplitude is the variation or displacement of a wave from its mean value. With sound waves, it is the amount to which air particles are removed, and this amplitude of sound or sound amplitude is encountered as the loudness of sound. The quantity of energy taken by a wave is similar to the amplitude of the wave. A large energy wave is described by a high amplitude, a low energy wave is described by a low amplitude.
