noun Physics.

the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern ) at the edge of a shadow.

the bending of waves, especially sound and light waves, around obstacles in their path.

Origin of diffraction

1665–75; <New Latin diffrāctiōn- (stem of diffrāctiō) a breaking up, equivalent to Latin diffrāct(us) broken up (past participle of diffringere) + -iōn--ion. See dif-, fraction

/ (dɪˈfrækʃən) /

noun

physics a deviation in the direction of a wave at the edge of an obstacle in its path

any phenomenon caused by diffraction and interference of light, such as the formation of light and dark fringes by the passage of light through a small aperture

deflection of sound waves caused by an obstacle or by nonhomogeneity of a medium

Cultural definitions for diffraction

diffraction

The breaking up of an incoming wave by some sort of geometrical structure — for example, a series of slits — followed by reconstruction of the wave by interference. Diffraction of light is characterized by alternate bands of light and dark or bands of different colors.

Medical definitions for diffraction

diffraction

[ dĭ-frăk′shən ]

n.

Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture.

Scientific definitions for diffraction

diffraction

[ dĭ-frăk′shən ]

The bending and spreading of a wave, such as a light wave, around the edge of an object. See more at wave.
