Diffraction is the deviation of waves from straight-line propagation without any change in their energy due to an obstacle or through an aperture. The diffracting object or aperture effectively …

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 …

Dec 5, 2016 · The meaning of DIFFRACTION is a modification which light undergoes especially in passing by the edges of opaque bodies or through narrow openings and in which the rays …

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.

Jul 2, 2025 · Core Definition: Wavefront Manipulation and Huygens’ Principle Diffraction refers to the deviation of waves from rectilinear (straight-line) propagation when encountering an …

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 phenomenon of the bending of waves as they pass around an obstacle or through an aperture. Instead of continuing in a straight line, the waves spread out.

The breaking up of an incoming wave by some sort of geometrical structure — for example, a series of slits — followed by reconstruction of the wave by interference. Diffraction of light is …

In this case, diffraction is the key, and essentially enables lines -- almost any type -- to bend and filter light.
