Question

Pitch of a sound depends upon the

• A. Amplitude
  
• B. Frequency
• C. Wavelength
• D. Wave velocity

Answer 1

The correct option is B Frequency

The pitch of the sound depends upon the frequency of the sound. If the frequency of vibration is higher, the sound is shrill and of high pitch. On the other hand, if the sound is said to have lower pitch, then it has a lower frequency of vibration. The voice of a woman has higher pitch than that of a man.

Hence, the correct answer is option (b).
