The intensity of sound (W/m $2$ ) varies as
A) the distance squared.
B) 1 over the distance.
C) 1 over the distance squared.
D) the distance.

Question

Quizplus · Accepted Answer

The intensity of sound in a three-dimensional space decreases with the square of the distance from the source, following the inverse square law. This means as you move away from the sound source, the intensity decreases as the square of the distance, hence the correct option is "1 over the distance squared."
