The amplitude of a variable is a measure of its change over a single period. The maximum height observed in the wave is called as Amplitude. It is denoted by A and is given in decibels (dB). The sine wave is represented as
Where A is amplitude and $\omega$ is angular frequency. The Amplitude Formula is given by
Where D is the distance traveled by the wave and
F is the frequency of the wave.
Amplitude Formula is used to the amplitude of the given wave if its distance and frequency are known.
