Advanced Physics

Unique small scale version of the famous cavendish experiment to verify Newton&#39s Law of Gravity and measure the Universal Gravitational Constant, G. This unit is remarkable for measuring the tiny value of G by simple, easily-understood means.

Set of equipment for studying the Zeeman Effect in the mercury green line at 545.1 nm.

Reliable and dramatic demonstration of the magnetic force between two current-carrying parallel conductors. Safely applies a large current to two pivoting brass tubes.

Display version of the Foucault 1851 experiment to demonstrate the Earth&#39s rotation. The 57&quot high unit contains a maintained pendulum whose precession rate can also be used to calculate latitude or time.

The Franck-Hertz Apparatus II is an 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). New

The Hall Effect is the generation of a side-to-side voltage in a conductor or semiconductor carrying a current when it is placed in a magnetic field. The effect is widely used in magnetic field sensors.

Comprehensive set of equipment with built in He-Ne laser. Top quality optical glass components allow over 75 experiments in geometric and physical optics. This product has a 90 day lead time. Market standard for this type of product.

High precision interferometer with interchangeable optics for Michelson or Fabry-Perot setups. 200 MM precision geared lead screw for fine adjustment. This product has a 90 day lead time. Market standard for this type of product.

Set of equipment for studying the nuclear magnetic resonance of protons in hydrogen and fluorine and measuring the gyromagnetic ratio, Lande factor, and nuclear magnetic moment of these nuclei. Includes permanent magnet, oscillator, frequency

The Phase and Group Velocity Apparatus (oscilloscope not included) uses sound waves in the ultasonic region to clearly illustrate and distinguish the often poorly understood phase and group velocity concepts. It permits precise measurements of the

Set of equipment for studying the photo-emission of a mixed alkali photocathode. Precise , stable illumination and bias control for excellent results. This product has a 90 day lead time. Market standard for this type of product.

Precision apparatus for measuring Planck&#39s Constant includes a mercury discharge lamp, vacuum photocell, set of mercury-line interference filters, and control unit. High quality amplifier yields results for h to better than 3%.
