Principle
In this experiment, for various LEDs (light emitting diodes) the
wavelength is determined by means of a grating using the subjective
method.
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
At which wavelength does an LED emit light? The wavelength is
characteristic of the colour of the light. Determine the wavelength
of LEDs by means of measurements and observations using a
diffraction grating.
