Two types of this phenomenon are named for Fraunhofer and Fresnel.
Two types of this phenomenon are named for Fraunhofer and Fresnel. A form of this phenomenon named for William Lawrence Bragg and William Henry Bragg occurs when light passes through a crystalline structure. Monochromatic coherent light is needed to observe the interference patterns caused by this phenomenon in Young's double-slit experiment, and this phenomenon is used to separate wavelengths of light in a namesake "grating." For 10 points, name this phenomenon where light bends around obstacles.
