A Conceptual Question

  1. Sep 18, 2007 #1
    I am asked to define the phase of a complex function (a wave) in words and physically. I don't know a better way than to draw two different sine functions and show the phase difference on the graph.....Any suggestions?

    Not much more to it. You could write a wave equation -

    [tex]\phi = e^{i(kx - \omega t)}[/tex]

    and transform with a phase change

    [tex]\phi ' = e^{i(kx - \omega t + \theta)}[/tex]

    What kind of wave? A quantum wave function? A classical wave?
