Answer:
Amplitude, A = 5 m
Explanation:
It is given that, the vertical height of an ocean from a crest to trough is 10 meters.
The attached figure shows the vertical height from a crest to a trough is 10 m. We know that the maximum displacement of the wave is called its amplitude. A represents the amplitude of wave. It is the distance from the baseline to the crest or to the trough.
So, the amplitude of the ocean wave must be equal to half of wave's height i.e. 10/2 = 5 meters.
