What Is the Difference Between the Crest and Trough?

In waves, the crest appears as the highest point, while the trough is the lowest, forming a dip or valley in the wave's motion. The crest, also called the peak, forms the maximum height of every wave, including water waves, radio waves and electrical waves. The distance and height between the trough and crest varies depending on the type of wave and local conditions, such as wind speed and direction.
