| reflection coefficient | 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's law; also equal to 1 minus the ratio of the effective pore areas available to solute and to solvent. (05 Mar 2000) |

| angle of reflection | <optics> The angle that a ray reflected from a surface makes with a line drawn perpendicular to this surface. It is equal to the angle of incidence. (05 Mar 2000) |

| reflection | 1. The act of reflecting, or turning or sending back, or the state of being reflected. Specifically: The return of rays, beams, sound, or the like, from a surface. See Angle of reflection, below. "The eye sees not itself, But by reflection, by some other things." (Shak) The reverting of the mind to that which has already occupied it; continued consideration; meditation; contemplation; hence, also, that operation or power of the mind by which it is conscious of its own acts or states; the capacity for judging rationally, especially in view of a moral rule or standard. "By reflection, . . . I would be understood to mean, that notice which the mind takes of its own operations, and the manner of them, by reason whereof there come to be ideas of these operations in the understanding." (Locke) "This delight grows and improves under thought and reflection." (South) 2. Shining; brightness, as of the sun. 3. That which is produced by reflection. Specifically: An image given back from a reflecting surface; a reflected counterpart. "As the sun water we can bear, yet not the sun, but his reflection, there." (Dryden) A part reflected, or turned back, at an angle; as, the reflection of a membrane. Result of meditation; thought or opinion after attentive consideration or contemplation; especially, thoughts suggested by truth. "Job's reflections on his once flourishing estate did at the same time afflict and encourage him." (Atterbury) 4. Censure; reproach cast. "He died; and oh! may no reflection shed Its poisonous venom on the royal dead." (Prior) 5. <physiology> The transference of an excitement from one nerve fibre to another by means of the nerve cells, as in reflex action. See Reflex action, under Reflex. Angle of reflection, the angle which anything, as a ray of light, on leaving a reflecting surface, makes with the perpendicular to the surface. Angle of total reflection. <optics> Same as Critical angle, under Critical. Synonym: Meditation, contemplation, rumination, cogitation, consideration, musing, thinking. Origin: Written also reflexion. Source: Websters Dictionary (01 Mar 1998) |
| reflection factor | <microscopy> The ratio of reflected light from a surface to the incident light. This is sometimes called the coefficient of reflection. Unless especially stated it takes into account both specular and diffuse reflection. (05 Aug 1998) |
| reflection X-ray microscopy | <technique> A method of producing enlarged images by means of X rays. In this method the radiation is totally reflected at glancing incidence from polished concave mirrors or from the curved surfaces of single crystals by Bragg reflection. The problem of aberration corrections still limits the resolution obtainable. (05 Aug 1998) |
| grating, reflection | <microscopy> An opaque (metallic) diffraction grating from which incident light is reflected -to form a spectrum, or to act as a micrometric standard for opaque specimens. (05 Aug 1998) |
| interference reflection microscopy | <procedure> An optical technique for detecting the topography of the side of a cell in contact with a planar substrate and for providing information on the separation of the plasmalemma from the substrate. Interference between the reflections from the substrate medium interface and the reflections from the plasmalemma medium interface generate the image. (18 Nov 1997) |
| Fresnel reflection | <microscopy> Process by which radiant flux is reflected from an optically plane boundary between two transparent dielectric materials. (05 Aug 1998) |
| absorption coefficient | <physics> Measures the degree of wave absorption defined as the fraction of wave energy lost as the wave travels a unit distance. See: absorption. (15 Jan 1998) |
| activity coefficient | <chemistry> The factor by which the value of a concentration of a solute must be multiplied to determine its true thermodynamic activity. (06 May 1997) |
| attenuation coefficient | 1. <radiobiology> Compton: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing as a result of Compton effect interactions. 2. Linear: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing due to all absorption and scattering processes. 3. Pair Production: That fractional decrease in the intensity of a beam of ionising radiation due to pair production in a medium through which it passes. 4. Photoelectric Effect: That fractional decrease in the intensity of a beam of ionising radiation due to photoelectric effect in a medium through which it passes. (16 Dec 1997) |
| biological coefficient | Rarely used term denoting the energy expended by the body at rest. (05 Mar 2000) |
| Bunsen's solubility coefficient | The milliliters of gas STPD dissolved per milliliter of liquid and per atmosphere (760 mm Hg) partial pressure of the gas at any given temperature. (05 Mar 2000) |
| velocity coefficient | The rate of transformation of a unit mass of substance in a chemical reaction. (05 Mar 2000) |
| recombination coefficient | <radiobiology> The rate of recombination of positive ions with electrons (or negative ions) in a gas, per unit volume, divided by the product of the particle densities of the two species (positive ions and electrons/negative ions) involved. (09 Oct 1997) |
| mass attenuation coefficient | <physics> The mass attenuation coefficient, u/p, of a material for uncharged ionising particles is the quotient of DN/N by pdl, where DN/N is the fraction of particles that experience interactions in traversing a distance dl in a material of density p. (16 Dec 1997) |
| reflection coefficient |
(fiber optic) The fraction of light power reflected backward at the fiber end face. This accounts for about a .2 to .3 dB loss, typically.

| reflection coefficient |
The ratio of the voltages corresponding to the reflected and incident waves at the antenna's input terminal (normalized to some impedance Z0). The return loss is related to the input impedance Zin and the characteristic impedance Z0 of the connecting feed line by: Gin = (Zin - Z0) / (Zin+Z0).
