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 pieces', …

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。

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 small moving …

The bending of a wave around the edges of an opening or an obstacle is called diffraction. Diffraction is a wave characteristic that occurs for all types of waves. If diffraction is observed for a phenomenon, it …

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 light.

Jul 2, 2025 · Fraunhofer diffraction is commonly observed in applications involving lenses and telescopes, where focusing elements effectively bring the observation point to infinity. The diffraction …

May 27, 2025 · Diffraction is the phenomenon where waves bend, spread, or interfere when they encounter an obstacle or pass through a narrow opening. The effect is subtle yet profound.

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 dimmer maxima to …

Diffraction describes a specialized case of light scattering in which an object with regularly repeating features (such as a diffraction grating) produces an orderly diffraction of light in a diffraction pattern.

Diffraction is when waves bend around the corner of an obstacle. ... It is most easily seen when a wave spreads out after passing through a gap.
