Discrete emission spectra
... The electron waves in de Broglie’s model can only vibrate in discrete modes. As a consequence, the energy of the electrons can only take certain values: it is quantized. An electron wave which vibrates at a high frequence (i.e. high energy) can give up some of its energy. Because the allowed vibrati ...
