The energy of a sound wave is most closely

related to the wave's

(1) frequency (3) wavelength

(2) amplitude (4) speed

The energy of a sound wave is most closely related to the wave’s " (3) wavelength" although it should be noted that other roles do indeed play a role as well.

Answer : Option B) Amplitude

Explanation : The energy of a sound wave is most closely related to wave's amplitude.

Amplitude of a sound wave is usually a longitudinal pressure wave. Which means the amplitude of sound wave determines the size of the compressions and rarefactions in the same direction as the direction of motion.
