Experimental Unit of Planck's Constant-RSDI-1


This experimental unit uses the photoelectric effect, where electrons stimulated by incoming light create an electric current, to experimentally determine the value of Planck's constant (h).

Description

Details

The measurement of Planck's constant has being carried out in many institutions with a variety of approaches.
This experimental unit uses the photoelectric effect, where electrons stimulated by incoming light create an electric current, to experimentally determine the value of Planck's constant (h).
This unit also encourages students to get a fundamental understanding of the quantum character of light and to gain experience with experimental skill related to photoelectric effect.
