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 sound waves and audio signals (which relates to the volume) conventionally refers to the amplitude of the air pressure in the wave, but sometimes the amplitude of the displacement (movements of the air or the diaphragm of a speaker) is described.
Wave amplitude is the measure of the maximum displacement of a wave from its resting position, or equilibrium. Put simply, it’s the height of a wave from its highest point to its lowest point. In a sound wave, for example, the amplitude determines the loudness of the sound.
The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced.
Amplitude determines the loudness of sound waves and the brightness of light waves. In a sinusoidal wave, amplitude is the distance from the midpoint to the crest or trough. Amplitude does not affect the wavelength or frequency of a wave, but higher amplitude means more energy.
Amplitude. As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from its undisturbed position. Key fact. It is important to note that the...
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.
Amplitude is a measurement of the amount of energy transferred by a wave. Amplitude on a transverse wave is typically measured as the distance between the peak or trough of the...
Amplitude, frequency, wavenumber, and phase shift are properties of waves that govern their physical behavior. Each describes a separate parameter in the most general solution of the wave equation. Together, these properties account for a wide range of phenomena such as loudness, color, pitch, diffraction, and interference.
