1. A beam of electron enters a uniform 1.2 T magnetic field. (a) Find the energy difference between electrons with spins parallel and antiparallel to the field. (b) Find the wavelength of the radiation that can cause the electrons with spins parallel to the field to flip so that their spins are antiparallel.
