Question
The pitch of which wave is the minimum?
- Wave-1
- Wave-2
- Wave-3
- Wave-4
Hint:
Pitch depends on frequency.
The correct answer is: Wave-4
- Pitch of a sound wave depends on its frequency.
- The higher the frequency of a sound wave, the higher is its pitch.
- The lower the frequency of a sound wave, the lower is its pitch.
- Therefore, wave-4 has the minimum pitch.
- So, the correct option is d.
