Finding B-field from Zeeman effect pattern

  1. Feb 9, 2013 #1
    Hey

    I have this problem

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


    A source which emits a line at 500nm is found to exhibit the normal Zeeman effect
    when placed in a magnetic field. Calculate the magnetic field given that the separation
    of adjacent components in the Zeeman pattern is 12.0pm.





    2. Relevant equations

    I have this equation from my text book

    ΔE = μbBgmj



    3. The attempt at a solution

    I am assuming that I need to use the fact given about the distance of the components in the pattern to find ΔE and then rearrange for B, but I am not sure how to do that.

    Any help would be appreciated

    Thanks

    Recall that E = hf and f = c/λ. See if you can write ΔE in terms of Δλ and λ of the source.
