Topics covered:
- Amount of energy
- Quantum leap
- Electron collision
- Excitation energy
Principles and objectives:
Electrons are accelerated in a tube filled with neon vapor. The excitation energy of neon is determined from the distance between equidistant minima of the electron current in a variable opposing electric field. The study is divided into two parts:
- Record the intensity of the counter current Is in a Franck-Hertz tube as a function of the anodic voltage Ua.
- Determine the excitation energy Ea from the position of the minima or maxima of the current intensity by forming the difference.
Comments:
Fascinating Nobel Prize-winning experiment (Franck-Hertz 1925). Compact neon tube in a robust housing - ready for use with a short warm-up time. Control unit compatible with Ne and Hg tubes. Easy-to-use software for control, data acquisition, and evaluation.
