Which of the following defines the amplitude of a wave? Is the answer A measure of the length of in intensity of the wave?

Answer 1

No, the answer is not "A measure of the length of in intensity of the wave." The correct definition of amplitude is "The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position." Amplitude is a measure of the magnitude or strength of the wave, specifically referring to the distance between the equilibrium position and the highest point of the wave's oscillation.
