This Franck-Hertz Apparatus is designed for college students to demonstrate the existence of quantized states. The experiment can be performed in less time because the use of Argon tube eliminates the need for tube heating (as in the case of a Mercury filled tube). The data can be recorded manually, or directed to an oscilloscope or computer for display. For additional background information and a brief history, please click here to refer to the Foothill college website where our devices are presently in use.
