MCQ
The energy of a wave depends on:
✓
Amplitude of the wave
B
Phase of the wave
C
Timbre of the wave
D
Shape of the wave
✓
Answer
Correct option: A.
Amplitude of the wave
The energy of a wave is directly proportional to amplitude square and hence it increases with the increase in the amplitude of the wave.
A wave with greater amplitude will release more energy when it falls back to sea level than a wave of lesser amplitude.
