Atoms
hvif = Eni – Enf
(12 11)
Since both nf and ni are integers, this immediately shows that  in
transitions between different atomic levels, light is radiated in various
discrete frequencies The various lines in the atomic spectra are produced when electrons
jump from higher energy state to a lower energy state and photons are
emitted These spectral lines are called emission lines
