Question

The amount of work done to produce a sound determines which property of sound waves?
A.
wavelength
B.
amplitude
C.
pitch
D.
frequency

Answers

GPT-5 mini
B. amplitude

Reason: The work done on the source adds energy to the wave, which increases the oscillation amplitude (and thus the sound's loudness/intensity). Pitch (frequency) depends on the vibration rate, and wavelength depends on frequency and wave speed.
