Adding Two Wave Functions

  1. Sep 5, 2005 #1
    I am not looking for any answers, just some guidance.

    Consider case (c), (case (c) involved two waves with equal wavelength and amplitude, but with some arbitrary phase difference), and write the two waves as

    [tex]y1(x) = Acos((\frac{2*\pi*x}{\lambda}))[/tex]
    [tex]y2(x) = Acos((\frac{2*\pi*x}{\lambda}) + \phi) [/tex]

    where [tex]\lambda[/tex] and [tex]A[/tex] are the common wavelength and amplitude of the two waves and [tex]\phi[/tex] is their phase difference. Calculate the sum wave [tex]y(x) = y1(x) + y2(x)[/tex] and find an expression for the amplitude of the sum wave in terms of [tex]A[/tex] and [tex]\phi[/tex].

    Find an expression for Amplitude in terms of the amplitude?? What exactly is this question asking?
