The Franck-Hertz Experiment (1961)
The Franck-Hertz experiment demonstrates that mercury atoms can only absorb energy in discrete packets, confirming the atomic theory proposed by Niels Bohr. The experiment involves colliding electrons with mercury atoms and measuring the resulting energy transitions. As electrons gain energy through acceleration, they can transfer specific amounts of energy to mercury atoms, causing observable drops in current when the energy matches the discrete energy levels of the atoms. The findings support the idea that atoms exist in quantized energy states and can emit light when returning to lower energy states.
