Terms of diffraction

Airy's disk
—The diffraction pattern produced by a circular aperture such as a lens or a mirror.

Bragg's law
—An equation that describes the diffraction of light from plane parallel surfaces.

Diffraction limited
—The ultimate performance of an optical element such as a lens or mirror that depends only on the element's finite size.

Diffraction pattern
—The wave pattern observed after a wave has passed through a diffracting aperture.

—A device used to produce diffraction patterns of materials.

Fresnel diffraction
—Diffraction that occurs when the source and the observer are far from the diffraction aperture.

Interference pattern
—Alternating bands of light and dark that result from the mixing of two waves.

—The distance between two consecutive crests or troughs in a wave.

X-ray diffraction
—A method using the scattering of x rays by matter to study the structure of crystals.
