The amplitude of the oscillations change as time goes on is the more rigid (or less compressible) the medium, the faster the speed of sound.
In physics, amplitude refers to the greatest displacement or distance that a point on a vibrating body or wave can move relative to its equilibrium location. It is equivalent to the vibration path's half-length.
Distance between the wave's resting position and its highest displacement is known as amplitude. The number of waves that pass by a specific location each second is known as its frequency. Period: the amount of time needed for a wave cycle to complete.
Sound waves' relative strength, which we experience as loudness or volume, is known as amplitude. Decibels (dB), which stand for sound pressure level or intensity, are used to measure amplitude.
