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.
- >
- <
- =
- 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.
