Principle

This experiment on diffraction at an optical grating not only provides convincing proof of the ability of (visible) light to undergo interference, and hence of its wave character; but it is also well suited to determine the wavelength of selected colours of the spectrum. Moreover, it is sure to motivate students who will be impressed by the ability to determine with simple means such small physical quantities as the wavelength of light.

Benefits

  • Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
  • Extension with others sets at anytime, no additional light sources needed, recognition value for students

Tasks

Produce a diffraction spectrum using an optical grating and determine the wavelengths of red and green light.
