Basic Franck-Hertz Experiment Heater (115 V, 50/60 Hz)
$ 1,399.00
Highly evacuated electron tube containing mercury in a heating chamber for demonstrating the discrete nature (quantization) of the energy released by free electrons in collisions with mercury atoms, and for determining the excitation energy of the mercury resonance line (61S0 – 63P1) at 4.9 eV. The electron tube must be heated in the chamber to generate the necessary mercury vapor pressure to achieve a sufficiently high probability of collisions between electrons and mercury atoms. The tube has a plane parallel electrode system consisting of an indirectly heated oxide cathode with aperture, a grid, and a collecting electrode. The tube also has a front plate with printed tube symbol visible from a distance. There is a thermostat controlling the electric heating chamber, which is a lacquered metal housing with two observation windows, opening with spring clip for a thermometer, and thermally insulated carrying handle.
