In the structure of the waves, the following parts of wave are found:
1. Wave Crest: The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
2. Wave Trough: The trough of a wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position.
3. Wave Length: The distance between two successive crests of a wave is called its wave length.
