Which of the following statements is false?

  1. A drum produces a low pitched sound because it vibrates with a low frequency.

  2. A whistle has a high frequency and therefore, produces a sound of a higher pitch.

D Correct answer
Explanation

The loudness of a sound depends upon its amplitude. The higher the amplitude, the louder is the sound and vice-versa. The pitch or shrillness of a sound is determined by its frequency. The higher the frequency, the shriller is the sound and vice-versa. Hence, option (4) is false. A feeble sound will have a low amplitude, not a high amplitude.
