1: Under high resolution, the spectral line of Sodium (Z = 11)around 589 nm resolves into two lines at 589.5 nm and 588.9 nm dueto spin-orbital coupling splitting the 1p shell into2P3/2 and 2P1/2.
Part A: Calculate the difference in energy between the2P3/2 and 2P1/2 states.
Part B: From this energy difference, estimate the magnitude ofthe internal magnetic field.
Part C: If a magnetic field of 1 Tesla is applied to the Sodiumatoms, the lines split further. Please construct an energy leveldiagram to show the split lines. How many distinct lines would youexpect?
