(a) State Bohr’s condition for the emission of radiation when an electron in the hydrogen atom makes a transition between two stationary states.
(b) Name the spectral series obtained when the principal quantum number of the final state is (i) 1, (ii) 2 and (iii) 3.
(c) Using the ideas of energy difference between stationary states and the electromagnetic spectrum, explain clearly why the series mentioned in part (b) respectively appear in the ultraviolet, visible and infrared regions. Your answer must refer to relative photon energies and wavelength ranges.
