refraction refraction definition. A change of direction that light undergoes when it enters a medium with a different density from the one through which it has been traveling — for example, when, after moving through air, it passes through a prism. Note: Lenses and other optical instruments work through refraction of light.

Physics When waves interact with matter, they can be reflected, transmitted, or a combination of both. Waves that are transmitted can be refracted.

- Image by Flickr.com, courtesy of Jule_Berlin. In relation to your eyes, refraction refers to how light waves bend as they pass through your cornea and lens. Your eye's ability to refract light determines its ability to focus light, which establishes how well you see. Your eye has a refractive error if it cannot focus an image sharply. Determining the lens prescription needed to correct the error is called a refraction or refraction assessment. Your eye's ability to refract light depends on the overall length of the eye and the curvature of the eye's surface (cornea).

refraction 1. The deflection of a wave, such as a light or sound wave, when it passes obliquely from one medium into another having a different index of refraction. 2. Astronomy The apparent change in position of a celestial object caused by the bending of light rays as they enter Earth's atmosphere.

refracting telescope telescope definition. A device used by astronomers to magnify images or collect more light from distant objects by gathering and concentrating radiation. The most familiar kind of telescope is the optical telescope, which collects radiation in the form of visible light. It may work by reflection, with a bowl-shaped mirror at its base, or by refraction, with a system of lenses.

refraction dynamic refraction Determination of the refract-ive state of the eye when accommodation is stimulated, as distinguished from static refraction which is the determination of the refractive state of the eye when accommodation is at rest or paralysed.

Difference Between Diffraction and Refraction Both diffraction and refraction involve change of direction of waves. When a wave encounters an obstacle, bending or spreading occurs, which we call diffraction. On the other hand, waves refract when they travel from one medium to another.ntensity of the fringes decreases as we move along either side of the central maxima. Refraction. When a wave passes from one medium to another at any angle except 90° and 0°, its line of travel changes at the interface due to the change in velocity of the wave. This is what we call refraction.

- Refraction occurs when a beam of light is bent, and is caused by a change in the speed of the beam as it passes from one transparent medium to another.

refraction The bending of a wave, such as a light or sound wave, as it passes from one medium to another medium of different density. The change in the angle of propagation depends on the difference between the index of refraction of the original medium and the medium entered by the wave, as well as on the frequency of the wave. Compare reflection.

refraction Also called astronomical refraction. the amount, in angular measure, by which the altitude of a celestial body is increased by the refraction of its light in the earth's atmosphere, being zero at the zenith and a maximum at the horizon.

- Because they refract the rays of light in the same manner as the rain drops. Because the light vapours of the air, which are condensed as the sun sets, refract the rays of light, and produce red rays. Ions in the air act like drops of mist; they refract sunshine and make rainbows after rain. In the mean while another Prism abc is to be fixed next after that hole g, to refract the trajected Light a second time.

What is the difference between a refracting and reflecting telescope? A reflecting telescope uses the reflection of light as its method of focus. A refracting telescope uses the refraction (or bending) of light as its method of focus. Reflecting telescopes are much more useful than refracting telescopes, as chromatic aberration is not an issue, and have a significantly larger range than refractors.

Matter and the Study of Radiation In the refraction of a ray of light, the angle through which light is refracted depends on wavelength; the angle of refraction is greater for shorter wavelengths than it is for longer ones. Consider white light passing through the slit of a narrow diaphragm and then through a glass prism, as in Figure 3.
