- 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.

Why are crests and troughs aligned?
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.
trough - the lowest point below the rest position; amplitude - the maximum displacement of a point of a wave from its rest position
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.
Waves and Sound. Troughs: In transverse wave, the points where the particles of the medium have maximum displacement in the negative direction are called troughs. The lowest point of the wave is called the trough. In Figure, point C and G are troughs.
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. One such property is amplitude.
Definition. The trough is the lowest point of a wave, where the displacement of the medium is at its minimum.
