Homework Help: Michelson morley

    1. The problem statement, all variables and given/known data

    Suppose the calibration constant of your spectrometer is 0.5, and suppose the wavelength of the light is λ = 550 nm. How much does the micrometer reading change during the movement of M2 that generates the passage of 50 fringes?
    2. Relevant equations

    possibly delta(l)= delta(n)*lambda /2
    delta(m)= delta(l)/K , K being some constant to find the distance

    3. The attempt at a solution

    possibly delta(l)=50* 550 nm/ 2 delta(m)= delta(l)/K = 13750 nm/(.5) =27500 nm

    Is this from Modern Physics for Engineers? I have seen this problem before. When I get home in about an hour or two I'll try to digg up the answer.
