Franck Hertz Experiment Without Datalogger & Software

Franck Hertz Experiment Without Datalogger & Software
Make Dinesh Scientific Model DS-605
Product Description
Apparatus used for the experiment consist of a tube containing low pressure gas, fitted with four electrodes. The four electrodes are: an indirectly heated, oxide coated, cathode as an electron source, two grids G and G and a plate A, which serves as an 1 2 electron collector. The experiment was designed to measure this loss, so they needed some way to distinguish between electrons with different amounts of kinetic energy. This is where the grid comes in.

Specifications
To observe the neon spectral bands formation in franck- hertz tube and to record the franck-hertz characteristic curve for neon to find out the excitation energy. To study the effect of filament voltage and anode plate voltage on the characteristic curve. The complete setup should include
