Question

As compared to a whistle, vibrations produced by drum has

• A. large amplitude
• B. small amplitude
• C. high frequency
• D. low frequency

Answer 1

The correct option is D

low frequency

Correct option: (D)

1. frequency is defined as the speed of vibration and it determines shrillness or pitch of sound.
2. It is measured as number of oscillations or vibrations
3. Vibrations produced by drums is less than whistle, thus drum's frequency is less than whistle.
   

Incorrect options: (A),(B),(C)

1. Amplitude defines the intensity of sound whether loud or soft not regarding vibrations.
   Thus (A) and (B) are incorrect options.
2. Drum produces less vibrations than a whistle, so its not high frequency-option (C) is incorrect answer.

Hence as compared to a whistle ,vibrations produced by drum has less frequency.
