The Ultrasonic Grating Apparatus is both a unique demonstration of the interaction of longitudinal sound waves and transverse light waves and also a method for the precise determination of the speed of sound in liquids, which is otherwise difficult to do in the undergraduate lab. The core of the...

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. It is associated with several well-known systematic errors, some of which can be eliminated by...

Surface Plasmon Resonance is an analytical technique used for detecting and tracking a wide variety of surface processes such as DNA and protein interactions, drug mechanisms, immunoassays, anodic stripping, corrosion, gas detection, and many more. Demonstrate the principles of SPR analysis Use a...

Precision apparatus for measuring Planck's 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%. This product has a 90 day lead time. Market standard for this type...

The Force Table is a great tool for teaching composition and addition of vectors, and it provides a platform for additional forces. It can be used to study the following: the concept of force, the direction of a force, the equilibrium of a material point, the intensity of different forces, the Rule...

Set of equipment for studying the Zeeman Effect in the mercury green line at 545.1 nm. Includes a 1.0T electromagnet that allows longitudinal or transverse viewing, a mercury lamp, interference filter and lens, a 2.0MM gap Fabry-Perot etalon, a CCD camera and capture card, and evaluation software....

Display version of the Foucault 1851 experiment to demonstrate the Earth's rotation. The 57" high unit contains a maintained pendulum whose precession rate can also be used to calculate latitude or time. This product has a 90 day lead time. Market standard for this type of product.
