PLANCK’S CONSTANT USING LED TRAINER

PLANCK’S CONSTANT USING LED TRAINER

Category: Electronics

Model No:IE-129

Planck`s Constant determination using LED is a useful setup which illustrates the basic concept of the Quantum Mechanics. The setup familiarizes the concept of photon energy and explains how it is related to its frequency. Setup is mainly designed to evaluate Planck`s Constant.  For this purpose five LEDs of different colors are included with the setup. This setup facilitates to determine the Planck`s Constant by measuring the voltage drop across LEDs.
