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 effect when placed in a magnetic field. 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!
