Question

What does the trough of a wave refer to?

Answer 1

Troughs of Waves. 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. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.

Step-by-step explanation:

Answer 2

A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. Crests and troughs on a transverse wave are shown in Figure 1. Figure 1: Crests and troughs in a transverse wave. A crest is a point on the wavewhere the displacement of the medium is at a maximum.
