Description
The Franck–Hertz apparatus is a self-contained teaching unit for performing the classic Franck–Hertz experiment, used in atomic physics to demonstrate electron-impact excitation and support learning around discrete atomic energy levels. It incorporates a xenon-filled electron tube (Thyratron) in a glass envelope with multiple electrodes that enable controlled electron emission, acceleration, and collection, so excitation effects can be observed as changes in measured tube current.
To operate the tube, laboratory supplies are required for the heater and for setting the anode–cathode accelerating voltage. For practical measurement in teaching labs, the apparatus includes an integrated current amplifier and an inbuilt 9 V battery. This allows very small currents to be read using ordinary bench meters when a sensitive mirror galvanometer is not available, improving usability for routine demonstrations and student practical work.
The apparatus supports repeatable experiments where students vary the accelerating voltage and record the resulting current behaviour, enabling clear discussion of excitation events in xenon, excitation potential concepts, and the importance of stable geometry and consistent measurement technique. It is well suited to senior secondary and university teaching laboratories, as well as instrumentation training where a reliable, evidence-based atomic excitation demonstration is required.
Important use note: Use appropriate laboratory power supplies for heater and electrode voltages, and follow standard electrical safety procedures for bench-top operation.
FAQs
Q: What does the Franck–Hertz experiment demonstrate?
A: It demonstrates electron-impact excitation and supports instruction on discrete atomic energy absorption during excitation.
Q: What tube and gas does this apparatus use?
A: It uses a xenon-filled electron tube (Thyratron) with multiple electrodes in a glass envelope.
Q: Why does the apparatus include an amplifier and 9 V battery?
A: The tube current is very small. The built-in amplifier, powered by the inbuilt 9 V battery, boosts the signal so it can be measured on standard bench meters.
Q: What external supplies are required?
A: External supplies are required for the tube heater and for the anode–cathode accelerating voltage used to run the experiment.
Q: Who is this apparatus intended for?
A: School and university teaching labs and training environments covering atomic excitation, electron tubes, and low-current measurement.
