Reflection Coefficient
reflection coefficient[ri′flek·shən ‚kō·i‚fish·ənt] (physics) The ratio of the amplitude of a wave reflected from a surface to the amplitude of the incident wave. Also known as coefficient of reflection. Reflection Coefficient the ratio of the radiant flux reflected by a body to the radiant flux incident on it. The concept of an amplitude reflection coefficient, that is, the ratio of the amplitudes of the reflected and incident waves, is sometimes used —for example, for radio waves. In general, the reflection coefficient is the sum of a direct reflection coefficient and a diffuse reflection coefficient. reflection coefficient
re·flec·tion co·ef·fi·cient (σ), a measure of the relative permeability of a particular membrane to a particular solute; calculated as the ratio of observed osmotic pressure to that calculated from van't Hoff law; also equal to 1 minus the ratio of the effective pore areas available to solute and to solvent.re·flec·tion co·ef·fi·cient (σ) (rĕ-flek'shŭn kō'ĕ-fish'ĕnt) A measure of the relative permeability of a particular membrane to a particular solute; calculated as the ratio of observed osmotic pressure to that calculated from van't Hoff law.
