Diffraction at a slit and Heisenberg's uncertainty principl

Article No: P2230101

The distribution of intensity in the Fraunhofer diffraction pattern of a slit and at an edge is measured. The results are evaluated both from the wave pattern view point, by comparison with Kirchhoff's diffraction formula, and from the quantum mechanics standpoint to confirm Heisenberg's uncertainty principle.

Key Features

Quantum mechanical versus wave theory viewpoints are discussed observing light transversing a slit
A measured diffraction pattern can be explained by quite different theories
The famous "uncertainty principle" can be confirmed in this setup
