NTC-22.01.6 “Franck-Hertz Experiment”

Br0.00

The educational laboratory stand is designed to introduce students to the Franck-Hertz experiment, for determining the critical potential of an atom and confirming the discrete nature of the internal energy of atoms.

 

Categories: , , ,

The stand is designed as a desktop panel device.

The housing includes front and rear panels.

On the front panel of the stand, the following components are installed:

  • Schematic diagram illustration.
  • Controls for adjusting the retarding voltage.
  • Controls for adjusting the accelerating voltage.
  • Control for adjusting the degree of cathode heating.
  • Measurement system indicators.

The rear side of the stand contains electrical protection circuitry, switches for turning on/off the measuring devices, a USB port, and sockets for connecting oscilloscope probes.

Inside the stand there is a power supply unit, a measurement system, and a board for computer communication. The measurement system is intended for measuring and displaying the investigated parameters (current, voltage).

The laboratory stand comes with software and teaching materials.
