In sodium, one of the two yellow lines has a wavelength of 589.76 nm and is the transition from the 4PM2 state to the 451/2 state. If a sodium atom is placed in a magnetic field due to the anomalous Zeeman effect, it can be shown that the energy splitting may be determined by i/ = yBBextng. If the magnitude of the external magnetic field is 2.90 T, determine the difference in wavelength (in m) between the shortest and longest wavelength between these two states. :m
