Which phrase correctly defines the amplitude of a wave?(1 point)

Responses

A. the horizontal distance from the crest of one wave to the crest of the next wave

B. the vertical distance from the crest or trough of a wave to the equilibrium

C. the horizontal distance from the trough of one wave to the trough of the next wave

D. the vertical distance from the trough of a wave to the crest

B. the vertical distance from the crest or trough of a wave to the equilibrium

The correct answer is B. The amplitude of a wave is the vertical distance from the crest or trough of the wave to the equilibrium position. To understand this concept, it is helpful to visualize a wave as a repeating pattern of crests (the highest points) and troughs (the lowest points). The amplitude is the measure of how high (or low) these points are relative to the equilibrium position. To find the amplitude of a wave, you would measure the vertical distance between the crest or trough and the equilibrium position.

The correct answer is B. the vertical distance from the crest or trough of a wave to the equilibrium.
