The effects of diffraction of light were first carefully observed and characterized by Francesco Maria Grimaldi, who also coined the term diffraction, from the Latin diffringere, 'to break into …

衍射（英语：diffraction）是指波遇到障碍物时偏离原来直线传播的物理现象。 在经典物理学中，波在穿过狭缝、小孔或圆盘之类的障碍物后会发生不同程度的弯散传播。

If the first term is large in comparison to the second term, the diffraction dominates over the nonlinear phenomena, leading to defocusing of the ripple.

Oct 17, 2025 · Diffraction, the spreading of waves around obstacles. Diffraction takes place with sound; with electromagnetic radiation, such as light, X-rays, and gamma rays; and with very …

Nov 17, 2022 · Diffraction is the bending or spreading of light waves around an obstacle. The obstacle can be an aperture or slit whose size is approximately the same as the wavelength of …

Diffraction is the spreading of a wave as it passes through a gap or around an edge. Diffraction effects are greatest when waves passes through a gap with a width roughly equal to their …

Diffraction can send a wave around the edges of an opening or other obstacle. A single slit produces an interference pattern characterized by a broad central maximum with narrower and …

此外，在 电子显微镜 或 X射线形貌器 （X-ray topography device）中，衍射衬度（diffraction contrast）可以用来检验晶体中的缺陷以及局部应变场（local strain field），进行金属薄膜材 …

光在传播过程中，遇到障碍物或小孔时，光将偏离直线传播的路径而绕到障碍物后面传播的现象，叫光的衍射（Diffraction of light）。
