Franck-Hertz experiment with a Hg tube

 Product No: P2510311

Principle

Electrons are accelerated in a tube filled with mercury vapour. The excitation energy of mercury is determined from the distance between the equidistant minima of the electron current in a variable opposing electric field.

Tasks

  1. To record the countercurrent strength Ι in a Franck-Hertz tube as a function of the anode voltage U.
  2. To determine the excitation energy E from the positions of the current strength minima or maxima by difference formation.

What you can learn about

  • Energy quantum
  • Electron collision
  • Excitation energy
