With no magnetic field, the spectral line representing the transition from the ²P_1/2 state to the ²S_1/2 state in sodium has the wavelength 589.76 nm (see Figure 8.16). This is one of the two strong yellow lines in sodium. Calculate the difference in wavelength between the shortest and longest wavelength between these two states when placed in a magnetic field of 2.50 T.
