China Wholesale electron-atom collision Manufacturers – LADP-9 Apparatus of Franck-Hertz Experiment – Basic Model – Labor
China Wholesale electron-atom collision Manufacturers – LADP-9 Apparatus of Franck-Hertz Experiment – Basic Model – Labor Detail:
Introduction
This Franck-Hertz experiment apparatus is a cheap instrument to demonstrate the existence of Bohr atomic energy levels. Experimental results can be acquired by manual data recording, or viewed on an oscilloscope, or processed using a digital storage oscilloscope. No oscilloscope is necessary if an optional data acquisition (DAQ) card is ordered for use with a PC via USB port. It is an ideal teaching apparatus for physics laboratories at colleges and universities.
