dif·frac·tion

 (dĭ-frăk′shən)
n.
Change in the directions and intensities of a group of waves after passing by an obstacle or through an aperture whose size is approximately the same as the wavelength of the waves.

[New Latin diffrāctiō, diffrāctiōn-, from Latin diffrāctus, past participle of diffringere : dis-, apart; see dis- + frangere, to break; see bhreg- in Indo-European roots.]

diffraction

(dɪˈfrækʃən)
n
1. (General Physics) physics a deviation in the direction of a wave at the edge of an obstacle in its path
2. (General Physics) 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
3. (General Physics) deflection of sound waves caused by an obstacle or by nonhomogeneity of a medium
[C17: from New Latin diffractiō a breaking to pieces, from Latin diffringere to shatter, from dis- apart + frangere to break]

dif•frac•tion

(dɪˈfræk ʃən)

n.
a modulation of waves in response to an obstacle, as an object, slit, or grating, in the path of propagation, giving rise in light waves to a banded pattern or to a spectrum.
[1665–75; < New Latin diffrāctiō, derivative of Latin diffringere to break up]

dif·frac·tion

(dĭ-frăk′shən)
The bending or turning of a wave, such as a light wave, when it encounters an obstacle, such as an edge, or a hole whose size is similar to the wavelength of the wave. The patterns made by the diffraction of waves can be useful for understanding the minute structures of objects. The diffraction patterns made by x-rays as they pass between the atoms of a molecule, for example, are studied in order to determine the molecule's overall structure. See more at wave.

diffraction

An effect caused when, after passing an obstacle or through a narrow slit, waves (e.g. of light) interfere with each other and may bend or spread.
