Diffraction

Diffraction, английский
- The "spreading" of waves into the lee of obstacles such as breakwaters by the transfer of wave energy along wave crests. diffracted waves are lower in height than incident waves.
- Дифракция
- Deviation of the direction of propagation of a radiation, determined by the wave nature of radiation, and occurring when the radiation passes the edge of an obstacle.
- A wave property which creates deviation from a straight line when the beam passes near an edge of an opaque object. deviation of part of a beam, determined by the wave nature of radiation and occurring when the radiation passes the edge of an opaque obstacle.
- Light curves or travels around small circular objects.
- The changing of direction (bending or spreading) that occurs when a light wave interacts with an opening or barrier
- (1) in acoustics, the reflection of a wave front when passing the edge of an ultrasonically opaque object. (2) in radiation technologies, a special case of scatter, where coherently scattered photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also xray diffraction.
- (1) в акустике - отражение волнового фронта при прохождении края непрозрачного для ультразвука объекта. (2) в радиационных технологиях - особый случай рассеяния, когда когерентно рассеянные фотоны подвергаются интерференции или усилению, что приводит к образованию структур, указывающих на рассеивающую среду. см. также дифракция рентгеновских лучей.
- (1) in radiographic testing, special case of scatter, where coherently scattered (full intensity is retained) photons undergo interference or reinforcement, resulting in patterns indicative of the scattering medium. see also x-ray diffraction. (2) in ultrasonic testing, deflection of a wavefront when passing the edge of an ultrasonically opaque object.15
- Deflection of a wavefront when passing the edge of an ultrasonically opaque object.7,22
