Question

In the case of sound waves, _________shows its volume or loudness.

  1. Frequency 
  2. Wavelength 
  3. Amplitude
  4. Time

hintHint:

The height of the wave is responsible for loudness.

The correct answer is: Amplitude


    • Loudness of a sound wave depends on its amplitude.
    • The maximum displacement or distance traveled by a point on an oscillating body or shaft, measured from the equilibrium position.
    • Loudness is directly proportional to the amplitude.
    • So, the correct option is c.
