Refract, английский
Refractaire, французский
Refractairite, французский
Refracted, английский
Refracted beam, английский
- Beam transmitted in the second medium when an ultrasonic beam is incident at an acute angle on the interface between two media having different sound speeds.
- Beam transmitted in the second medium when an ultrasonic beam is incident at an acute angle on the interface between two media having different sound speeds.7,22
Refracted beam (ut), английский
The beam that occurs in the second medium when an ultrasonic beam passes obliquely from one medium to another when each medium has different sound velocities.
Refracted index, английский
Characterizes the way a transparent optical material bends or refracts light.
Refracted index profile, английский
A description shown in the form of a diagram illustrating how the optical density of an optical fiber alters across its diameter.
Refracting medium, английский
Refracting telescope, английский
That through which objects are seen directly through its double object-glass.
Refractio, латинский
Refractio [onis, f] (lucis), латинский
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
Refraction (ut), английский
Change in direction of an ultrasonic beam as it passes obliquely through the interface between two materials with different acoustic velocity; see snell’s law.
