Light passing through a narrow opening in the blinds, causing bright and dark shadows and patterns to fall across the floor is an example of defraction.
- the breaking up of a ray of light into dark and light bands or into the colors of the spectrum, caused by the interference of one part of a beam with another, as when the ray is deflected at the edge of an opaque object or passes through a narrow slit
- a similar breaking up of other waves, as of sound or electricity
Origin of diffractionMedieval Latin diffractio ; from Classical Latin diffractus: see diffract
Origin of diffractionNew Latin diffrāctiō, diffrāctiōn-, from Latin diffrāctus, past participle of diffringere : dis-, apart; see dis– + frangere, to break; see bhreg- in Indo-European roots.
diffraction - Computer Definition
The process by which the propagation of radiant waveforms or light waves is modified as those waves encounter an obstacle or discontinuity, or exit one medium and enter another. Some of the waves deviate from their paths, i.e., bend, by diffraction. See also knife-edge diffraction, reflection, and refraction.
