Deriving the Doppler Effect

  1. Feb 3, 2008 #1
    1. The problem statement, all variables and given/known data

    I have a problem that asks to derive the doppler effect for the two different cases of a moving observer and a moving source.

    2. Relevant equations

    I should get f' = f*(v +/- vo)/(v +/- vs) as my general equation, where f' is the observed frequency and f is the frequency of the wave.

    3. The attempt at a solution

    I wish I had more work to show, but I'm not really sure how to derive formulas. Where should I begin?

    Nevermind, I figured it out. Wavelength changes with a moving source and velocity of the sound wrt the observer changes when the observer is moving.
