Answer:
Amplitude
Step-by-step explanation:
The amplitude of wave is is the maximum displacement of the wave from its respt position. It can also be seen as the distance from the center line to the trough or o the crest
The amplitude of wave is related to the energyu carried by the wave.
If the amplitude of a wave is high, then the wave is of high energy. Also, if a ave has a low amplitude, then the wave is a low energy wave
