101Absorption coefficient — The absorption coefficient α is a property of a material. It defines the extent to which a material absorbs energy, for example that of sound waves or electromagnetic radiation. Wallace Sabine was a pioneer of this concept in acoustics and… …
102Absorption band — An absorption band is a range of wavelengths (or, equivalently, frequencies) in the electromagnetic spectrum which are able to excite a particular transition in a substance. See absorption spectrum. Since energetic transitions can take place in… …
103Absorption spectrum — A material s absorption spectrum shows the fraction of incident electromagnetic radiation absorbed by the material over a range of frequencies. An absorption spectrum is, in a sense, the opposite of an emission spectrum.Every chemical element has …
104Absorption (optique) — Pour les articles homonymes, voir Absorption. Spectre de transmission de l atmosphère. Dans le visible, les pertes résultent principalement de la diffusion Rayleigh, alors que dans l infrarou …
105Absorption des rayons X — Spectrométrie d absorption des rayons X La spectrométrie d absorption des rayons X aide à déterminer la structure d un matériau. Elle a l avantage d être sélective quant à l espèce atomique observée. Sommaire 1 Histoire 2 Dispositif expérimental …
106Absorption law — In algebra, the absorption law is an identity linking a pair of binary operations.Any two binary operations, say $ and %, are subject to the absorption law if:: a $ ( a % b ) = a % ( a $ b ) = a .The operations $ and % are said to form a dual… …
107Absorption interstellaire — Loi d extinction interstellaire standard depuis les rayons X jusqu à l infrarouge proche. Est représentée l extinction en magnitudes en fonction de la longueur d onde pour une extinction visuelle AV = 1 mag. Les données proviennent de Morrisson… …
108absorption rate — overhead absorption rate; = recovery rate The rate or rates calculated in an absorption costing system in advance of an accounting period for the purpose of charging the overheads to the production of that period. Absorption rates are calculated… …
