● No preheating needed by using Argon gas tube
● Multiple measurement modes: manually taking data points, directly observing on oscilloscope, or software automatic processing (software optional)
● Argon tube visible through a window with backlight
● Stable and reliable.
The LEAI-32 Franck-Hertz Experiment Apparatus can demonstrate the existence of Bohr atomic energy levels. Experiment results can be acquired by manually point taken, or directly observed on an oscilloscope, or automatic processed by software (optional). It is an ideal teaching apparatus for physics laboratories in colleges and universities.
Experiment contents:
1.Observe the relationship curve between plate current and accelerating voltage on oscilloscope
2.Understand the processes 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 1st excitation potential by using software, learn automation technique. (optional)
