Introduction

This LEAI-31 Franck-Hertz experiment apparatus can demonstrate the existence of Bohr atomic energy levels. Experimental results can be recorded by manual data taking, viewed on an oscilloscope, or acquired using a built-in data acquisition (DAQ) card for PC via USB port. No oscilloscope is necessary when using the built-in DAQ card with a PC. It is an ideal teaching apparatus for physics laboratories at colleges and universities.

The instruction manual contains comprehensive materials including experimental configurations, principles and step-by-step instructions. Please click Experiment Theory and Contents to find more information about this apparatus.

Using this instrument, the following experiments can be conducted:

1. Observe the relationship curve between plate current and accelerating voltage

2. Understand the process of electron-atom collision and energy exchange

3. Calculate the 1^st excitation potential of Argon atom from experimental data

4. Using the acquired 1^st excitation potential to calculate Planck’s constant
