Homework Help: Snapshot graph of Superposition

  1. Sep 2, 2013 #1
    1. The problem statement, all variables and given/known data
    The figure is a snapshot graph at t = 0s of two waves approaching each other at 1.0 m/s. Draw six snapshot graphs, stacked vertically, showing the string at 1s intervals from t = 1s to t = 6s.

    2. Relevant equations

    3. The attempt at a solution
    Apparently I'm an idiot because this question is very easy. I literally shifted the graphs according to their velocity vector over 1m after each second. What am I doing wrong?

    You realize that the image shown for t=0 is one graph, D(x), not two graphs. You might want to attach an image of what you did at, say, t=3.
