diffraction maximum
91Holography — (from the Greek, ὅλος hólos whole + γραφή grafē writing, drawing) is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the… …
92Angular resolution — describes the resolving power of any image forming device such as an optical or radio telescope, a microscope, a camera, or an eye. Definition of terms Resolving power is the ability of the components of an imaging device to measure the angular… …
93Introduction to quantum mechanics — This article is an accessible, non technical introduction to the subject. For the main encyclopedia article, see Quantum mechanics. Quantum mechanics …
94Disque d'Airy — Tache d Airy Exemple de tache d Airy simulée par ordinateur La nature ondulatoire de la lumière fait que celle ci est diffractée après le passage à travers un trou. Plus la taille du trou diminue, plus l effet de la diffraction est visible. Le… …

96Microscopy — is the technical field of using microscopes to view samples and objects that cannot be seen with the unaided eye (objects that are not within the resolution range of the normal eye). There are three well known branches of microscopy, optical,… …
97X (RAYONS) — Dans la suite continue des radiations électromagnétiques que l’on sait produire, depuis les longueurs d’onde très courtes de l’ordre de 10 size=1漣4 nm jusqu’à celles de l’ordre de plusieurs kilomètres, on appelle rayons X les radiations comprises …
98Solar power satellite — A solar power satellite, or SPS or Powersat, as originally proposed would be a satellite built in high Earth orbit that uses microwave power transmission to beam solar power to a very large antenna on Earth. Advantages of placing the solar… …
99Metal ions in aqueous solution — A metal ion in aqueous solution is a cation, dissolved in water, of chemical formula [M(H2O)n]z+. The solvation number, n, determined by a variety of experimental methods is 4 for Li+ and Be2+ and 6 for elements in rows 3 and 4 of the periodic… …
100Wave — A wave is a disturbance that propagates through space and time, usually with transference of energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic… …
