Planck Constant Kit
Product Code : EL-PLE-15741
Eduscope India is a leading Planck Constant Kit
Quick Answer: The Planck Constant Kit is a photoelectric-effect apparatus that gives schools and colleges dependable physics lab equipment India for experimentally determining Planck's constant — a precise, export-ready choice for institutions upgrading their laboratory equipment school India wide.
Construction and Specifications
The kit is equipped with a set of colour filters at 635nm, 570nm, 540nm, 500nm and 460nm wavelengths, allowing the photoelectric effect to be studied across a range of light frequencies. Light is detected using a sensitive photovacuum tube with a dark current below 0.003 µA, illuminated by a 12V / 35W tungsten halogen light source fitted with crocodile-clip and banana-clip terminals for straightforward wiring to the control unit. The working distance between the light source and the filter is maintained at 300mm to 400mm to keep readings consistent. The acceleration voltage is held to an accuracy better than 2%, allowing Planck's constant to be determined with a measurement error under 15% of the standard value of 6.63 x 10-34 Js. Each kit is supplied with a user manual and control unit, sample data for teacher reference, and a video/audio guide to the kit's operation.
