Using the Bohr model, determine the energy, in joules, necessary to ionize a ground-state hydrogen atom. German-born physicists James Franck and Gustav Hertz obtained the experimental evidence of the presence of these states. The Bohr model is the simplest model. Neils Bohr, a Danish physicist in 1913 proposed a new model of atom. That is why we’re presenting this topic right now. Wie wir in folgenden Bild sehen, gibt es ein Beugungsbild wenn man einen Laser (Welle) auf ein Gitter schießt.
