Question

Given below are the sound wave forms of the voices of a boy and a girl. The amplitude of the boy’s voice is ____ the amplitude of the girl’s voice.

  1. >
  2. <
  3. =
  4. None of the above

Hint:

The frequency of the boy's voice is less than the girl's voice.

The correct answer is: =


    • The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. 
    • In this case, the amplitude is the same in both cases.
    • So, the correct option is c.
