1803, in optics, "to break up (a beam of light) by deflecting it from a right line," perhaps a back-formation fromdiffraction. In acoustics by 1825. Related:Diffracted;diffracting. *bhreg- Proto-Indo-European root meaning "to break." ...
Two possible approaches for the study of diffraction of light by a screen are the methods attributed, respectively, to Young and Fresnel. The connection between those two approaches is discussed in a way to clarify possible confusion or misunderstanding of the physical meaning of the contour wave ...
Moreover, the meaning of the complex degree of fractionality of the fractional Fourier transform is found to be related to the energy variation of the beam. Its influence on the phase-space representation of the optical beam is shown to be different compared with the diffraction through an ...

Diffraction grating definition: a band of equidistant, parallel lines, usually more than 5000 per inch (2000 per centimeter), ruled on a glass or polished metal surface for diffracting light to produce optical spectra.. See examples of DIFFRACTION GRATIN
