We are offering Franck-Hertz Experiment useful in Physics and Material Science Lab. This experiment verifies that:
It is possible to excite atoms by low energy electron bombardment.
- The energy transferred from electrons to the atoms always had discrete values.
- The values so obtained for the energy levels were in agreement with spectroscopic results.
- Thus the existence of atomic energy levels put forward by Bohr can be proved directly. It is a very important experiment and can be performed in any college or University level laboratory.
