What do we call the low point of a wave?

The low point of a wave is referred to as the trough. In oceanography and wave physics, a wave consists of alternating high points, known as crests, and low points, known as troughs. The trough represents the lowest part of the wave cycle, where the wave's energy is at its minimum. Understanding these terms is essential for studying wave behavior, including how waves interact with the shoreline and other environmental factors. The crest, on the other hand, is the top of the wave, while the terms wavelet and peak are not commonly used to describe standard wave structures in this context. Each component of the wave plays a crucial role in its overall behavior and impact on the environment.
