Question
If we pluck the string softly, we will decrease the ______ of the wave.
- Frequency
- Wavelength
- Amplitude
- All
Hint:
The distance of the crest from the centre line will be less.
The correct answer is: Amplitude
- If we pluck the string softly, we will decrease the amplitude of the wave.
- If we pluck it strongly, it will increase the amplitude.
- So, the correct option is c.
