Frank-Hertz Experimental Instrument
Product Code : EL-PLE-12621
This instrument is used for proving Bohr's theory of atomic energy level. It takes a tube filled with argon as a F-Htube. The experiment can be done under normal temperature, demanding no heating or temperature keeping. The spectrum amplitude curve can be plotted by means of point-measuring, it can also be observed directly on the screen of oscilloscope.
