Before going to learn what is amplitude formula, let us recall what is amplitude. The maximum displacement of any particle of a medium, from its state or a position of equilibrium, is called the amplitude. Amplitude is represented with 'A'. In a periodic function with a bounded range, the amplitude is half the distance between the minimum and maximum values. The amplitude is a height from the centerline to the peak or to the trough. Let us learn the altitude formula along with a few solved examples.
