Step-by-step explanation:
Energy is transferred from one place to another in the form of waves. Waves has two parts, the highest part of a wave is called the crest, whereas the lowest part is called trough. The distance between the crest and the trough of a wave is known as wave height. When we drop something in the water, waves are produced having high crest and trough means high wave length whereas waves produced on the solid body has low crest and trough means low wave height.
