The amplitude of a wave is the maximum amount of displacement of a particle in the position of rest. The amplitude measures the height of the wave from the mid-line, which can be calculated using amplitude formula. The total number of waves passing through a particular time is called as frequency. A wave can transmit more energy if it has higher frequency. The amplitude of a wave equation is the ratio of the distance travelled by the wave and the frequency of the wave.

Where,

A = Amplitude of Wave

D = Distance Traveled by the Wave

F = Frequency of the Wave

The amplitude formula can be used to find the amplitude of different waves like the sound waves. Also, click the amplitude calculator link provided below the amplitude of a wave equation to automatically calculate the amplitude.
