101Diffraction 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… …
102Polarizer — For the photographic filter, see Polarizing filter (Photography). A polarizing filter cuts down the reflections (top) and made it possible to see the photographer through the glass at roughly Brewster s angle although reflections off the back… …
103Electricity — (from the Greek word ήλεκτρον, (elektron), meaning amber, and finally from New Latin ēlectricus , amber like ) is a general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge. These include many… …
104Light field — The light field is a function that describes the amount of light traveling in every direction through every point in space. Michael Faraday was the first to propose (in an 1846 lecture entitled Thoughts on Ray Vibrations ) that light should be… …
105Hall effect — For the Colombian band, see The Hall Effect (band). The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular …
106Bond dipole moment — The bond dipole moment uses the idea of electric dipole moment to measure the polarity of a chemical bond within a molecule. The bond dipole μ is given by::mu = delta , d.The bond dipole is modeled as +δ mdash; δ with a distance d between the… …
107Coercivity — This article is about a property of magnetic fields. For other meanings, see Coercion (disambiguation). A family of hysteresis loops for grain oriented electrical steel (BR denotes remanence and HC is the coercivity). In materials science, the… …
108Momento dipolar de enlace — El momento dipolar de enlace o momento de enlace usa la idea del momento dipolar eléctrico para medir la polaridad de un enlace químico dentro de una molécula. El dipolo de enlace, μ, está dado por: . El dipolo de enlace está modelado como +δ δ …
109Fourier analysis — In mathematics, Fourier analysis is a subject area which grew out of the study of Fourier series. The subject began with trying to understand when it was possible to represent general functions by sums of simpler trigonometric functions. The… …
110Engineering drawing — Technical drawings An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items. Engineering drawing (the activity) produces engineering drawings (the documents). More than just the… …
