Franck-Hertz experiment with a Ne-tube
Article no. P2510315 | Type: Experiments
Fascinating Nobel Prize experiment (Franck-Hertz 1925)
- Suitable for demonstration and lab courses as well
- Compact neon tube in sturdy casing - ready to use due to short heat-up time
- Control unit compatible to Ne and Hg tube
- Easy-to-use software for control, data acquisition and evaluation
- Energy quantum
- Quantum leap
- Electron collision
- Excitation energy
Electrons are accelerated in a tube filled with neon vapour. The excitation energy of neon is determined from the distance between the equidistant minima of the electron current in a variable opposing electric field.
- To record the counter current strength I in a Franck-Hertz tube as a function of the anode voltage U.
- To determine the excitation energy E from the positions of the current strength minima or maxima by difference formation.
