Product Description

Plancks Constant Determination Box

Plancks Constant Determination Box — specification

The Plancks Constant Determination Box is one of our Atomic Physics Lab Equipment products, manufactured in Ambala Cantt and exported for physics training, testing and research.

This apparatus is designed to determine the approximate value of Planck Constant using the elbow voltage in the characteristics curves of a number of LEDs.

There are seven LEDs covering from deep blue at 470 nm to near IR 940 nm mounted on the box with sockets for voltage and current measurements.

By monitoring the voltage at which each LED begins to emit light a graph of energy input as a function of light emitted frequency can be plotted and an approximate value of Planck Constant can be deduced.

External 9V power source or 9V battery and connecting leads required.
