the amplitude of the wave.​


  1. Answer:

    Amplitude, A = 5 m


    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)


    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.
