Fraunhofer Diffraction Patterns

Diffraction is the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front. It is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow. Joseph von Fraunhofer (1787-1826) was a German optician
