Electron Energy Loss Investigation through the Nobel Prize Winning Franck-Hertz Experiment

Home \ experiment
Student Manual

Franck-Hertz experiment is a profound way of looking at the quantization of energy levels in an atom. A triode tube filled with mercury vapors is employed to accelerate electrons that in turn excite mercury atoms and energy transfer can be observed only for certain discrete values of energy of the colliding electrons. This implies that energy transfer to and from an atom can only be in fixed amounts, and hence a discrete atomic structure.

You can find an associated lecture on this experiment at the following link:

Software Code Comsoft for interfacing BK Precision’s Oscilloscope
Sample Results Franck Hertz Plots at different temperatures
Franck-Hertz curves taken by Shahzad Akhtar (2024)
Experiment Code 1.13
Version 15 May 2015, 2015-v1
