Question
Decreasing amplitude decreases _______.
- Vibration
- Force
- Pressure
- Direction
Hint:
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.
