Question

An increase in amplitude makes a sound wave _______.

  1. Mute
  2. Loud
  3. Decrease
  4. None

hintHint:

Loudness of a sound depends on its amplitude.

The correct answer is: Loud


    • The loudness of a sound depends on its amplitude.
    • Therefore, an increase in the amplitude makes a sound wave louder.
    • So, the correct option is b.
