Principle

When a laser beam falls on a grating, interference causes intensity minima and maxima to be formed behind the grating, and the wavelength of the laser beam can be determined from these positions.

Benefits

  • Curriculum-relevant DEMO Experiment in optics
  • Equivalence to the corresponding student experiment
  • Stable optical bench
  • Compact, simple construction

Tasks

  • Determining the wavelength of a laser with an optical grating
