Homework Help: Transverse Wave Interference

  1. Apr 30, 2009 #1
    1. The problem statement, all variables and given/known data
    Having two identical waves, knowing how much they're out of phase with each other, how can I know the amplitude of the resulting wave (as a factor of the original amplitude)?

    2. Relevant equations

    3. The attempt at a solution

    Write down two wavw equations, say
    A1 = Ao(sinwt + phy1) and A2 = Aosin(wt + phy2)
    Add them to find the amplitude of the resultant wave.
