Franck-Hertz Experiment

In 1914 Franck & Hertz experimentally proved that the energy transferred from electrons to atoms always has discreet values and the values obtained for energy levels are in agreement with spectroscopic results. Thus experimentally proving the Bhor’s Model. It is a landmark experiment and can e performed in any college lab. The experiment consists fo the following :• Argon filled tetrode • Filament Power Supply 3.6-4.3 continuously variable • Power Supply for VG K 1 1.
