The powder type of this phenomenon is a technique used to analyze crystalline solids.
The powder type of this phenomenon is a technique used to analyze crystalline solids. Application of this effect to crystal lattices and X-rays was pioneered by the father-son team of Bragg. In microscopes and telescopes, this phenomenon prevents angular resolution beyond a certain point. Types of this phenomenon are named for  Fraunhoffer and Fresnel. Interference patterns that occur due to this phenomenon resulted from Young's double slit experiment. A namesake grating can be used to separate light of different wavelengths. For 10 points, name this effect in which light bends around an object.
