China Wholesale Abbe Refractometer Quotes – LADP-10 Apparatus of Franck-Hertz Experiment – Advanced Model – Labor
China Wholesale Abbe Refractometer Quotes – LADP-10 Apparatus of Franck-Hertz Experiment – Advanced Model – Labor Detail:
Note: oscilloscope not included
The experimental instrument is an integrated experimental instrument with compact design, intuitive panel, complete functions and convenient operation. The power supply voltage for Franck Hertz tube is stable, and the key switch is used to switch and adjust. The amplifier for measuring micro current has good anti-interference ability. The experimental instrument can obtain stable and excellent experimental curve. The experimental instrument adopts the form of panel window and backlight, which can make students clearly observe the structure of Frank Hertz tube.
Experiments
1. Observe the relationship curve between plate current and accelerating voltage
2. Understand the processes of electron-atom collision and energy exchange
3. Calculate the 1st excitation potential of Argon atom from experimental data
4. Using the acquired 1st excitation potential to calculate Planck’s constant
