Cross section (physics) — A cross section is the effective area which governs the probability of some scattering or absorption event. Together with particle density and path length, it can be used to predict the total scattering probability via the Beer Lambert law. In… … Wikipedia
Scattering cross-section — The scattering cross section, sigma; scat, relates the scattering of light or other radiation to the number of particles present. In terms of area, the total cross section ( sigma;) is the sum of the cross sections due to absorption, scattering… … Wikipedia
Cross Tipperary — Cross Tipperary, formally the County of the Cross of Tipperary, was an Irish county comprising those lands within County Tipperary which were excluded from the County of the Liberty of Tipperary , the county palatine under the jurisdiction of the … Wikipedia
Extinction angle — An extinction angle is a term used in optical mineralogy and petrology, which described the angle at which cross polarized light dims, as viewed through a thin section of a mineral in a petrographic microscope … Wikipedia
Cretaceous–Tertiary extinction event — Artist s rendering of bolide impact Badlands nea … Wikipedia
Undulose extinction — is a geological term referring to the type of extinction that occurs in certain minerals when examined in thin section under cross polarized light. As the microscope stage is rotated, individual mineral grains appear black when the polarization… … Wikipedia
Mathematical descriptions of opacity — When an electromagnetic wave travels through a medium in which it gets absorbed (this is called an opaque or attenuating medium), it undergoes exponential decay as described by the Beer–Lambert law. However, there are many possible ways to… … Wikipedia
dinosaur — /duy neuh sawr /, n. 1. any chiefly terrestrial, herbivorous or carnivorous reptile of the extinct orders Saurischia and Ornithischia, from the Mesozoic Era, certain species of which are the largest known land animals. 2. something that is… … Universalium

Diffraction topography — (short: topography ) is an X ray imaging technique based on Bragg diffraction. Diffraction topographic images ( topographs ) record the intensity profile of a beam of X rays (or, sometimes, neutrons) diffracted by a crystal. A topograph thus… … Wikipedia
