Plancks Constant Manufacturer,Supplier and Exporter in India
Product Code : EL-AS-10820
Product Description
Comprising a phototube and control unit with built-in voltmeter and nanoammeter, the apparatus can be used with three LEDs of known wavelength (included) to learn about the relationship between the energy of emitted electrons and the wavelength of incident radiation.
A new spin on the classic method of calculating Planck's constant, this apparatus provides a simple and effective means of studying the photoelectric effect, gaining a good value for h, and exploring basic quantum mechanics.
Planck's constant can then be calculated approximately using the Planck-Einstein relation.
The in-depth notes include explanations of a range of phenomena and theory associated with the photoelectric effect and Planck's work alongside the experimental methods.
