Homework Help: Find the upper bound on the relative speed of the Earth and the ether

  1. Jul 23, 2013 #1
    1. The problem statement, all variables and given/known data

    "The Michelson-Morley experiment was conducted using an interferometer with L1 = L2 = 40m, lambda = 632nm, and maximum fringe separation d = 0.0022 fringes.
    Find the upper bound on the relative speed of the Earth and the ether, and clearly state the significance of the result in the context of the experiment."

    2. Relevant equations

    I'm going through all my Michelson-Morley notes and I found this equation:

    d = ((v^2)/(λc^2)) (L1 + L2)

    but I don't know if it's relevant!

    3. The attempt at a solution

    Honestly I have no idea... I can't find anything on 'upper bound' in my notes, I'm totally stumped. If anyone could help me out or point me in the right direction that would be brilliant :) Thank you!
