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

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.

Below are given some problems based on amplitude which may be helpful for you.

Given: y = 5 sin $\omega$ t

The equation is of the form y = A sin $\omega$ t. Hence the amplitude is A = 5.

Given: Distance D = 0.5 m, Frequency f = 5 Hz

The amplitude is given by A = $\frac{D}{F}$

= $\frac{0.5}{5}$

= 0.1 decibels.
