Diffraction

Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. In classical physics, the diffraction phenomenon is described as the interference of waves according the Huygens Fresnel principle. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to...

diffraction

The bending of light when it enters from one medium into another. For example, light bends as it travels from air into another substance, such as water. Diffraction also occurs when light enters from the air into a mineral, and the amount of diffraction varies among minerals.

Diffraction

• (n.) The deflection and decomposition of light in passing by the edges of opaque bodies or through narrow slits, causing the appearance of parallel bands or fringes of prismatic colors, as by the action of a grating of fine lines or bars.

diffraction

a process in which an incident wave, which propagates in a medium and encounters one or more obstacles, possibly limiting openings gives rise in this medium to another wave not interpretable by geometrical optics, called a diffracted wave

diffraction

diffract. Compare with effusion. The ability of a wave to bend around the edges of obstacles or holes. The effect is most noticeable when the obstacle or hole is comparable to the size of the wavelength.

Diffraction

Diffraction is a term applied to certain phenomena connected with the modification that rays of light undergo in passing close to the edge of an opaque body. Thus when a beam of direct sunlight is admitted into a dark room through a narrow slit, and falls upon a screen placed to receive it, there appears a line of white light bordered by coloured f...

Diffraction

Diffraction is a wave phenomenon - i.e. all types of wave can diffract. Diffraction means the bending of wave (change in direction) and it occurs whenever a wave passes near to an obstacle. Longer wavelength waves diffract through a greater angle than shorter wavelength waves. Do not confuse diffraction with refraction

diffraction

diffraction, bending of waves around the edge of an obstacle. When light strikes an opaque body, for instance, a shadow forms on the side of the body that is shielded from the light source. Ordinarily light travels in straight lines through a uniform, transparent medium, but those light waves that j...

Diffraction

Periodic scattering of moving objects when they collide with an orderly pattern of fixed objects. Diffraction always follows Bragg's Law {n*Wavelength=2*Spacing of fixed objects*sin(angle of scattering)}. This periodic scattering is useful in determining the spacing of the fixed objects since all other variables in the equation are know. In Electro...
