A hydrogen atom undergoes a transition from a 2p state to the 1s ground state. In the absence of a magnetic field, the energy of the photon emitted is 122nm. The atom is then placed in a strong magnetic field in the z-direction. Ignore spin effects;consider only the interaction of the magnetic field with the atom's orbital magnetic moment. a) How many different photon wave-lenghts are observed for the 2p-1s transition? What are the m1 values for the initial and final states for the transition that leads to each photon wavelength. b) One observed wavelength is exactly the same with the magnetic field as without. What are the initial and final m1 values for the transition that produces a photon of this wavelength. c) One observed wavelength with the field is longer than the wavelength without the field. What are the initial and final m1 values for the transition that produces a photon of this wavelength.
