A variables amplitude is a measure of its change over a single period. The maximum height perceived in the wave is termed as Amplitude. It is represented by A and is known in decibels (dB).

Where the distance covered by the wave is D and

The frequency of the wave is F.

Amplitude Formula is made use of in computing the amplitude of the specified wave if its frequency and distance are provided.

**Amplitude Solved Examples**

Underneath we have provided some sample numerical based on amplitude which might aid you.

**Question 1: **If y (= 5 sin ω t)represents the wave, find the amplitude of the wave?

**Solution:**

Given: y = 5 sin ω t

The equation is of the form

y = A sin ω t

Henceforth, the amplitude is A = 5.

**Question 2: **Compute the amplitude of the wave if a wave travels a distance of 0.5 m and has a frequency of 5 Hz.

**Solution:**

Given: Distance D = 0.5 m,

Frequency f = 5 Hz

The amplitute is given by
