Question
In the case of sound waves, ________shows its volume or loudness.
- Frequency
- Wavelength
- Amplitude
- Time
Hint:
The height of the crest.
The correct answer is: Amplitude
- Loudness of a sound wave depends on its amplitude.
- Therefore, the case of sound waves, amplitude shows its volume or loudness.
- So, the correct option is c.
