LEAI-31 Apparatus of Franck-Hertz Experiment-Completed
● No preheating needed by using Argon gas tube ● Multiple measurement modes: manually taking data points, directly observing on oscilloscope, or software automatic processing (optional)) ● Compact, stable, reliable and affordable.
This LEAI-31Franck-Hertz Experiment Apparatus can demonstrate the existence of Bohr atomic energy levels. Experiment results can be acquired through point-to-point taken manually, or observed on an oscilloscope directly, or automatic processed by software (with optional interface and software). It is an ideal teaching apparatus for physics laboratories in colleges and universities.
1.Observe the relationship curve between plate current and accelerating voltage on oscilloscope
2.Understand the process of electron-atom collision and energy exchange
3.Record measure data, plot curve, and calculate the 1st excitation potential of Argon atom
4.Automatic measurement of excitation potential by using software, learn automation technique.
