You are given two waves, a transverse wave that moves to the right f1(x) and a transverse wave that moves to the left f2(x), on a string. As the problem begins, the wave f1(x) is moving to the right at v1 = +1 m/s and the wave f2(x) is moving to the left at v2 = -1m/s. what is the shape of the wave after 3s?

  1. It will depend upon the amplitudes and phases of the two waves. You need to provide more information.

    You need to write equations
    Amplitude = f(x,t)
    for the two waves, and add them

    If the amplitudes are equal, you get a standing wave with nodes every half-wavelength
