The lowest point of a transverse wave is called the trough. It is the point on the wave where the displacement of the medium is at its maximum negative value. The crest is the opposite, being the highest point on the wave where the displacement is at its maximum positive value.
The lowest point of a wave is called the trough. It is the point where the wave's amplitude is at its most negative value.
The lowest point on a wave is called the trough. It is the point on the wave where the displacement of the medium is at its minimum and the wave energy is at its lowest.
The trough is the lowest point on a wave because it represents the point with the minimum amount of displacement from the equilibrium position. It is where the wave reaches its most negative amplitude, and it is opposite to the peak of the wave which represents the maximum displacement.
The time it takes a point on a wave to move from its lowest point to its highest point and back to its highest point again is called the period of the wave. It is the time it takes for one complete cycle of the wave to occur. The period is inversely related to the frequency of the wave, which is the number of complete cycles that occur in a unit of time.
