Calculate
the amplitude of the wave.​

Answer 1

Amplitude, A = 5 m

Step-by-step explanation:

Let a progressive wave is given by equation :

`y=5\sin (100\pi t-0.4\pi x)` .....(1)

The general equation of a progressive wave is given by :

`y=A\sin (\omega t-kx)` ....(2)

Here,

A is the amplitude of the wave

`\omega` is the angular frequency

k is propagation constant

We need to find the amplitude of the wave.

If we compare equations (1) and (2), we find that the amplitude of the given plane progressive wave is 5 m.
