Franck-Hertz Apparatus II, improved model of the well-known Franck-Hertz Apparatus (FHA001), featuring updated electronics with better stabilization and digital readouts for voltage and current (more robust, easier to read correctly)
Phase and Group velocity Precision apparatus uses sound waves to clearly show phase and group velocity concepts. Make precise measurements of the velocity of sound in three different liquids. Three measurement techniques allow characteristics to be examined
Zeeman Effect Apparatus, high resolution Fabry-Perot interferometer and a USB video camera. Swivel-mounted 1.0T electromagnet for conversion from transverse to longitudinal viewing. PC software captures and evaluates the interference pattern, Light Emission In Magnetic Field
