    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. It is the distance between the crest or trough and the mean position of the wave.

    Jun 12, 2024 · 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.

    The maximum magnitude of displacement, so this amount right here, whatever that distance is here, is called the amplitude. So we represent the amplitude with a capital A, and it's called the amplitude, and it's defined to be the maximum magnitude of displacement for that oscillator.

    A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave. A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time.
