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.
