Which term refers to the low points of waves?

The term that refers to the low points of waves is "troughs." In the context of wave terminology, crests represent the highest points of the wave, while troughs denote the lowest points. This distinction is critical in understanding wave properties, such as amplitude and wavelength. The amplitude is measured as the distance from a trough to a crest, reflecting the wave's energy. Understanding these terms helps in fields such as physics and engineering, where wave behavior is essential, for example in studying sound waves, light waves, or water waves. The other terms do not correctly refer to the low points of waves: peaks and crests refer to high points, while valleys can sometimes be colloquially used but are not the standard term in wave terminology.
