- amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. The amplitude of a pendulum is thus one-half the distance that the bob traverses in moving from one side to the other.

The amplitude of a wave is its maximum disturbance from its undisturbed position. Key fact It is important to note that the amplitude is not the distance between the top and bottom of a wave.
The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position. In a sense, the amplitude is the distance from rest to crest. Similarly, the amplitude can be measured from the rest position to the trough position.

The Anatomy of a Wave Video Tutorial explains the meaning of wavelength and amplitude, discusses how to count the number of waves in a diagram of a wave pattern, and describes how to calculate the wavelength and the amplitude from a diagram.
Wave amplitude describes the maximum displacement from the equilibrium position. In other words: how far away from the equilibrium position are the crests and troughs? Depending on the wave, the amplitude could describe energy, intensity, or even just height.
The pendulum oscillates around a central midpoint known as the equilibrium position. Marked on the diagram by an x is the measure of displacement, and by an A is the amplitude of the oscillations, this is the maximum displacement.
