Question
Given below are the sound waveforms of the voices of a boy and a girl. The pitch of the boy’s voice is ____ the pitch of the girl’s voice.
- >
- <
- =
- None of the above
Hint:
The pitch depends on the frequency. High frequency means high pitch.
The correct answer is: <
- The total number of waves produced in one second is called the frequency of the wave.
- The pitch of a sound depends on the frequency.
- It tells us about the frequency of the sound.
- Sound with high frequency has higher pitch then the sound with low frequency.
- Therefore, in the given sound waveforms, pitch of boy's voice is less than the pitch of girl's voice.
- So, the correct option is b.
