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.
