Question

The lowest point of a wave is called the

a. crest.
b. trough.
c. tide.
d. breaker.

Answer 1

A trough is the lowest point a particle in the medium sinks to in a wave. It is characterized by a minimum displacement of the medium at that point.

Step-by-step explanation:

A trough is the lowest point a particle in the medium sinks to in a wave. It is characterized by a minimum displacement of the medium at that point.

In a transverse wave, the particles move perpendicular to the motion of the wave, and the amplitude is the maximum distance from the equilibrium position to a trough (or crest).
