Standing Waves

  1. Oct 1, 2007 #1
    Hi, the question was,
    "Suppose that the wave represented by the graphs interfered with its OWN reflection.
    Sketch one standing wave interference pattern you would expect to observe. On your
    sketch, indicate the amplitude of each supercrest and supertrough, and the internodal
    distance (using either the time or distance axis)"

    So heres the Question image link,
    [​IMG]

    and by choosing any one of the graph, I have drawn a Standing wave, shown below.
    [​IMG]
    Red line = Incident
    Blue line = Reflected
    Green line = Standing wave

    I have read that IF a wave reflect, then it would have the same amplitude as the incident wave, and the reflected wave would also have the same frequency and wavelength as its incident wave.

    However, I do not have the confidence that my diagram is correct.
    I have labeled the Nodes and the Antinodes, but the rest I'm not too sure...
    could anyone please correct me?
