Franck-Hertz Experiment with Neon
Product Code : JA-PLE-4285
The Franck-Hertz Experiment with Neon (SKU JA-PLE-4285) shows how electrons lose energy to neon atoms in inelastic collisions, and that this energy is transferred only in discrete steps matching the energy levels of the atom. Because excited neon atoms emit visible light, students can see glowing zones between the cathode and the grid and watch them move as the accelerating voltage changes. This Franck-Hertz experiment with neon is used in B.Sc, M.Sc and engineering physics practicals.
Specifications
Electrons accelerated between the cathode and the grid excite neon atoms by inelastic collision; the excited atoms emit visible light, and the positions of the brighter zones depend on the potential difference between cathode and grid.

Applications of the Franck-Hertz experiment with neon
The experiment gives direct evidence for quantised atomic energy levels: the collector current falls each time electrons gain enough energy to excite neon, and the matching light zones can be seen and counted.
- Demonstrating discrete (quantised) energy levels in atoms
- Measuring the excitation energy of neon from the spacing of current minima
- Observing the visible glow zones and their shift with accelerating voltage
- Atomic physics practicals in B.Sc, M.Sc and engineering physics
- Supporting lessons on the Bohr model and atomic spectra
