For an unaffected transition from orbital 4 to orbital 2, calculate the wavelength of the light emitted. (7 significant figures) If exposed to a magnetic field of great strength, the Zeeman Effect occurs. For an electron in hydrogen undergoing a transition from the 4 I to the 2 s orbital, the spectral line splits, creating a change in wavelength for the mi = 1 and -1 states of approximately +0.0055nm.
