The smearing of Airy disks produced during this phenomenon is a criterion for resolving the output proposed by Rayleigh, and it is based on the principle that a point on a propagating wavefront can produce smaller waves.
A form of this phenomenon that results from interactions with sound waves in crystals is named for Schaefer and Bergmann, and one that occurs on sound waves in water is named for Debye and Sears. A form of this phenomenon in crystalls is named for Bragg.  Fresnel names the near-field form of this phenomenon, while Fraunhofer names the other regime.The smearing of Airy disks produced during this phenomenon is a criterion for resolving the output proposed by Rayleigh, and it is based on the principle that a point on a propagating wavefront can produce smaller waves. For 10 points, name this phenomenon inn which light appears to bend around an obstacle.
