Michelson experiment question/modern physics

  1. May 23, 2005 #1
    I dont know how to proceed on this question. It says:

    A shift of one fringe in the michelson-morley experiment would result from a difference of one wavelength or a change of one period of vibration in the round trip travel of light when the inferometer is rotated 90º What speed would michelson have compared for earth's motion through the either is the result was seen as one shift of a fringe?

    OK, it has been a while since I dabbled in optics. What optic eqs should I use?
