Definition. A trough is the lowest point of a wave, representing a position where the wave's displacement is at its minimum. This key feature is essential for understanding wave behavior, as it contrasts with the crest, which is the highest point.
A trough is a local minimum or low point in a wave pattern, occurring between two crests or peaks. It is a fundamental concept in the study of wave phenomena and is particularly relevant in the context of Young's Double Slit Experiment.

Definition. The trough is the lowest point of a wave, where the displacement of the medium is at its minimum.
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. The wave shown above can be described by a variety of properties.
The figure shows the crest of an incident wave being reflected in phase with respect to the incident wave as a crest. If the incident wave were a trough, the reflected wave would also be a trough. The amplitude of the reflected wave would be equal to the amplitude of the incident wave.

1. A wave is introduced into a thin wire held tight at each end. It has an amplitude of 3.8 cm, a frequency of 51.2 Hz and a distance from a crest to the neighboring trough of 12.8 cm. Determine the period of such a wave.
