Homework Help: Landé g factor in the Zeeman Effect

  1. Feb 20, 2013 #1
    1. The problem statement, all variables and given/known data

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

    2. Relevant equations

    E=hc/lambda, ΔE = - μ B

    3. The attempt at a solution

    So I've already gone through all the work of calculating ΔE, and μ and subsequently calculating B to be ~0.5T however I have a problem in that in the expression for my B I have ΔE on top and gμb at the bottom.

    I chose to select g = 2 as my Landé g factor however it's a little bit ambiguous, I'm not sure whether it ought to be g = 1 in which case my value for B would be doubled to ~ 1T

    Any help would be much appreciated thank you!
