Diffraction pattern definition: the distinctive pattern of light and dark fringes, rings, etc, formed by diffraction. See examples of DIFFRACTION PATTERN used in a sentence.
Diffraction of light in observational astronomy limits the ability of an imaging system to resolve fine details. The larger the aperture of the telescope, and the smaller the wavelength, the finer the angular resolution. This is a reason why telescopes have very large mirrors, in addition to ...
Deviation of the direction of propagation of a beam of light, which occurs when the light passes the edge of an obstacle such as a diaphragm, the pupil of the eye or a spectacle frame. There are two consequences of this phenomenon. First, the image of a point source cannot be a point...
