Principle

Monochromatic light is incident on a slit or an edge. The intensity distribution of the diffraction pattern is determined.

Benefits

  • learn that the transition region from light to shadow is not a sharp line, but a diffraction pattern
  • you can make use of diffraction patterns to determine properties of the objects causing them
  • simple setup with very few components

Tasks

  1. Measurement of the width of a given slit.
  2. Measurement of the intensity distribution of the diffraction pattern of the slit and of the edge.

What you can learn about

  • Intensity
  • Fresnel integrals
  • Fraunhofer diffraction
