Technical data

How are the energy and the colour of light connected?

Article no: P1418001

Principle

According to the findings of quantum physics, the energy of electromagnetic radiation (light) occurs only at discrete values. As a fundamental natural constant, Planck's constant h describes the increments of this energy gradation of light.

Benefits

Specified for the requirements of the german final secondary-school examinations
Especially for secondary schools
Quantum and wave optics in a student experiment

Tasks

Determine Planck's constant h by measurements and observations of light-emitting diodes.
