Drums can produce ultrasound.

  1. True
  2. False

hintHint:

False

The correct answer is 'False'.


    • Drums can produce audible sound.
    • Audible range of frequency for an average human ear is 20Hz-20kHz.
    • Sounds with frequencies more than 20kHz are ultrasounds.
    • So, the given statement is false.
