Question

Which property of sound waves decreases as the square of the distance from the source increases? A. Pitch
B. Intensity C. Wavelength D. Speed ​

Answer 1

Intensity is the property of sound waves that decreases as the square of the distance from the source increases. Option B is correct.

What is a sound wave?

A sound wave is produced when a medium begins to vibrate. When an entity vibrates, a pressure wave is formed, which causes sound.

As the square of the distance from the source increases, the intensity of sound waves decreases.

Sound intensity relationship

$\rm {I} = \frac{1}{r^2}$

$\rm \frac{I_2}{I_1} =\frac{r_1^2}{r_1^2}$

Hence, option B is correct.
