Question
In the case of sound waves, _________shows its volume or loudness.
- Frequency
- Wavelength
- Amplitude
- Time
Hint:
The height of the wave is responsible for loudness.
The correct answer is: Amplitude
- Loudness of a sound wave depends on its amplitude.
- The maximum displacement or distance traveled by a point on an oscillating body or shaft, measured from the equilibrium position.
- Loudness is directly proportional to the amplitude.
- So, the correct option is c.
