In the arctic regions, refraction sometimes causes the ice to resemble a huge wall, which is considered an indication of open water in that quarter.

Дендриты, русский
, минеральные агрегаты (иногда кристаллы) древовидной формы. образуются в результате быстрой кристаллизации по тонким трещинам или в вязкой среде. характерны для самородных элементов (au, ag, cu), оксидов марганца, льда и пр.

Refraction, английский
- The tendency of wave crests to become parallel to bottom contours as waves move into shallower waters. this effect is caused by the shoaling process which slows down waves in shallower waters.
- The change of direction or speed of light as it passes from one medium to another.
- Преломление, рефракция
- Process by which the direction of a radiation is changed as a result of changes in its velocity of propagation.
- The change of direction of propagation of any wave, such as an electromagnetic wave, when it passes from one medium to another in which the wave velocity is different. the bending of incident rays as they pass from one medium to another (e.g., air to glass).
- The change of the propagation direction when a wave comes from one medium into another one
- The directional shift or "bending" of light rays as they leave one density medium and enter a different one. or why your legs are short in water when viewed from the air.
- The bending of light as it passes between materials of different refractive index.
- 1. a change of direction of light rays as they enter a medium such as the eye 2. the measurement of the angle at which the light rays bend, as a test to see if someone needs to wear glasses
- A test to determine the best prescription to correct a refractive error (myopia, hyperopia, astigmatism).
- The change in direction of a light ray or a sound ray in passing from one medium to another. refectory
- Рефракция
- An inflection of the rays of light: that property of the atmosphere which bends the rays of light in their passage to the eye from a different density, and causes the altitude of heavenly bodies to appear greater than it really is, especially near the horizon. (see terrestrial refraction.)
- A wave phenomenon involving change of direction or bending. when a wave of any kind— light, sound, sonar, radar, etc.—passes between materials of different density, its behavior changes as it exits the old medium. and encounters the new one. there is reflection off the boundary and transmission into the new medium. the transmitted wave undergoes refraction when it approaches the boundary obliquely.
- The bending of light as it passes through a diamond or gemstone.
- Bending of light waves, which occurs when a light wave passes from one medium to another
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.
- Reorientation of radiation’s path by the medium through which it passes.
- Deflection of a wave due to a change in its speed as it passes from one material to another. see also refractometer.
- Change in direction of an acoustic wave as the ultrasonic beam passes from one medium into another having different acoustic speeds. a change in both direction and mode occurs at acute angles of incidence. at small angles of incidence, the original mode and a converted mode may exist simultaneously in the second medium.7
Indication, английский
- Индикация
- A situation or sign which suggests that a specific treatment should be given or that a condition has a particular cause sulpha drugs have been replaced by antibiotics in many indications. contraindication
- (1) notice given by a dealer (through autex) or customer of an interest in buying or selling stock, sometimes including specific volume and price; (2) approximation of where a specialist sees buy and sell interest to tighten the range to an opening price.
- Выражение интереса (бирж.)
- In nondestructive inspection, a response or evidence of a response, that requires interpretation to determine its significance.
- Nondestructive test response that requires interpretation to determine its relevance. these include such things as meter deflections, shadows on radiographs, blips on screens, or localized discolorations on surfaces. see also defect; discontinuity; indication, false; indication, nonrelevant. indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the significance of an indication. indication, false: test indication that could be interpreted as originating from a discontinuity where no discontinuity exists. compare defect; ghost; indication, nonrelevant. false indications are an economic liability for inspection because they must be investigated. indication, nonrelevant: indication due to misapplied or improper testing. may also be an indication caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation, or location.
- Nondestructive test response that requires interpretation to determine its relevance.4 see also defect; discontinuity; false indication; nonrelevant indication. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect.1 test response caused by geometry or by a physical condition that is not a discontinuity. indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.1
- Nondestructive test response that requires interpretation to determine its relevance. compare defect; discontinuity; indication, false; indication, nonrelevant. indication, false: (1) test indication that could be interpreted as originating from a discontinuity but that actually originates where no discontinuity exists in the test object. (2) indication due to misapplied or improper testing. compare indication, nonrelevant; defect. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect. test response caused by geometry or by a physical condition that is not a discontinuity (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.

- Nondestructive test equipment response to a discontinuity that requires interpretation to determine its relevance.4 in magnetic particle testing, a visible accumulation of magnetic particles that serves as evidence of a magnetic leakage field.
- Defect, discontinuity, false indication and nonrelevant indication. induced current magnetization: noncontact means for testing delicate ring shaped objects for circumferential discontinuities. the technique is based on the fact that a time varying current passing through an internal conductor, often a soft iron or laminated core, self-induces an encircling magnetic field. this time varying magnetic field will induce a secondary current circling through the ring. this secondary current then self-induces the toroidal magnetic field used for testing.
- Nondestructive test equipment response to a reflector, requiring interpretation to determine its relevance. compare crack; defect; discontinuity; indication, false.10 indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the indication’s significance.10 indication, false: test indication that originates where no discontinuity exists in the test object. compare defect; indication, nonrelevant.10 indication, nonrelevant: indication possibly caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance) or that is smaller than a relevant indication. compare indication, false and indication, relevant.10 indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation or location. compare indication, nonrelevant.10,19
