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

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