Schaefar and Bergmann name a type of this phenomenon governing sound waves in crystals, and when this phenomenon occurs for a circular opening it creates an Airy disc.
Schaefar and Bergmann name a type of this phenomenon governing sound waves in crystals, and when this phenomenon occurs for a circular opening it creates an Airy disc. Near-field and far-field varieties of this phenomenon depend on the value of the Fresnel number, who names a type of this phenomenon contrasting the "Fraunhofer" type. This phenomenon is predicted by Huygens principle when observing a wave move through a single slit, and Young's double slit experiment showed interference by using this phenomenon. For 10 points, name this bending of waves around obstacles.
