Wave consine equation

  1. Apr 22, 2014 #1
    This is about wave reflection and transmission.

    For an infinite string with a density change at x=0, consider an incident wave propagating to the right from x = -∞. The most general form is W = A cos(w(t-x/c)+θ), with amplitude A, angular freuqency w, time t, distance x (from origin), wave speed c and phase θ.

    I do not understand the term (t-x/c). Shouldn't it be just t since we're starting from infinity? Thanks!

    To me it looks like: t=time at your location, -x/c=time required to get from x to the origin at speed c.
