Question

Decreasing amplitude decreases _______.

  1. Vibration
  2. Force
  3. Pressure
  4. Direction

hintHint:

Damped vibrations.

The correct answer is: Vibration


    • As the loudness of the sound decreases, the amplitude decreases.
    • As the amplitude decreases, the vibrations also decrease.
    • So, the correct option is a.

    • The amplitude of a vibrating body continuously decreases during damped vibrations.
    • Because the frictional (resistive) force due to the surrounding medium causes the energy loss.
