This phenomenon produces an intensity profile when light is shined through two slits, as in an experiment by Thomas Young, and a namesake "grating" using this phenomenon.
In one case, this process produces an intensity function that varies as sinc-squared of position. In general, the output of this phenomenon is the Fourier transform of the transmission function in the limit where the parallel rays approximation can be used. This phenomenon has a (*) Fraunhofer type, and it limits image resolution to at most 1.22 times the wavelength. This phenomenon produces an intensity profile when light is shined through two slits, as in an experiment by Thomas Young, and a namesake "grating" using this phenomenon. For 10 points, name this process in which light rays ‘bend' around obstacles, usually contrasted with reflection or refraction.
