About this document
Franck-Hertz Experiment Overview by Suyash is a document available to read on EtoBox.
The Franck-Hertz experiment provided early evidence that atoms have discrete energy levels. In the experiment, electrons pass through mercury vapor and lose energy in quantized steps when exciting mercury atoms from the ground state to an excited state of 5 eV. The document describes the experimental setup, which uses an electron beam accelerated through mercury vapor. It measures the electron current at the anode to determine the energy lost by electrons during inelastic scattering from mercury atoms.
