MCQ
When we change sound to loud sound we increase its:
- AFrequency
- ✓Amplitude
- CVelocity
- DWavelength
✓
Answer
Correct option: B.
Amplitude
Loudness depends on the square of the amplitude of the wave.
That is, loudness$∝($amplitude$)2.$
Amplitude is the size of the vibration, and this determines how loud the sound is. Larger vibrations make larger amplitude, hence, louder the sound.
