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. Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.

Amplitude. The amplitude of a periodic variable is a measure of its change in a single period (such as time or spatial period). The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude (see below), which are all functions of the magnitude of the differences between the ...

Amplitude corresponds to the loudness of the sound. [BL] [OL] Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength. [Figure Support] The same speaker is capable of reproducing both high- and low-frequency sounds.
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. Amplitude is a measure of how big the wave is. Imagine a wave in the ocean. It could be a little ripple or a giant tsunami. What you are actually seeing are waves with different amplitudes. They might have the exact same frequency and wavelength, but the amplitudes of the waves can be very different. The amplitude of a wave is ...
