Question

The amplitude of a sound is the A. frequency of the sound. B. magnitude of displacement of a sound pressure wave. C. psychological aspect of sound related to frequency. D. amount of sound energy falling on a unit area. E. pitch.

Answer 1

Answer:

Option B. magnitude of displacement of a sound pressure wave

Explanation:

Amplitude is simply the maximum displacement of a wave from its mean position.

Answer 2

Answer:

B. magnitude of displacement of a sound pressure wave.

Explanation:

In physics, amplitude means the maximum displacement attained by a particle from a particular position. The particle could be a wave or an object. When such particle reaches its peak during displacement, we say such particle has attained its amplitude. An example of such particle is the sound wave.

The amplitude of a sound is a measure of the loudness of the sound. In other words, a higher amplitude means a louder sound and vice-versa.
