What is the significance of the characteristic in the Frank Hertz experiment?
It is due to the ionization of mercury atoms by collisions with the flying electrons emitted at the cathode.
It proves the wave nature of electrons.
It disproves the de Broglie equation.
It is the result of the destructive interference of the scattered electrons.

The Davisson-Germer experiment and the Frank Hertz experiment. The Davisson-Germer experiment demonstrated the wave nature of electrons through electron diffraction, and verified the de Broglie equation. The experimental setup included an electron gun, collimator, target, and detector. The scattered electrons produced a diffraction pattern and the dual nature of matter was verified. The Frank Hertz experiment verified the existence of discrete energy states in atoms, and the graph of collected current vs accelerating voltage showed a characteristic peak due to the ionization of mercury atoms.
The characteristic in the Frank Hertz experiment is due to the ionization of mercury atoms by collisions with the flying electrons emitted at the cathode, as proposed by Frank and Hertz.
