The Bohr model for an electron transition in hydrogen between quantized energy levels with different quantum numbers n yields a photon by emission with quantum energy:
This is often expressed in terms of the inverse wavelength or "wave number" as follows:
 
Going on, we can calculate the net energy (kinetic plus potential) of an electron in the   Bohr orbital of the H atom:
