Definition of i., fiz. kırılma, kırılım, refraksiyon in Turkish English dictionary

refraction

The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density

{n} a variation of the rays of light from a direct course

the bending of electromagnetic radiation by its passage through a medium of a high refractive index Light is refracted by passing through a lens, water, or the atmosphere

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 Simply put, the bending of incident rays as they pass from one medium to another, such as air to water

The process in which the direction of energy propagation is changed as the result of a change in density within the propagating medium, or as the energy passes through the interface representing a density discontinuity between two media In the first instance the rays undergo a smooth bending over a finite distance In the second case the index of refraction changes through an interfacial layer that is thin compared to the wavelength of the radiation; thus, the refraction is abrupt, essentially discontinuous See atmospheric refraction Compare reflection, diffraction, scattering

Change in direction of a wave as it leaves one medium and enters another. Waves, such as sound and light waves, travel at different speeds in different media. When a wave enters a new medium at an angle of less than 90°, the change in speed occurs sooner on one side of the wave than on the other, causing the wave to bend, or refract. When water waves approach shallower water at an angle, they bend and become parallel to the shore. Refraction explains the apparent bending of a pencil when it is partly immersed in water and viewed from above the surface. It also causes the optical illusion of the mirage

(1) The deflection, or bending, of the ray path of a seismic wave caused by its passage from one material to another having different elastic properties (2) Bending of a tsunami wave front owing to variations in the water depth along a coastline

The change in the direction of a ray of light, and, consequently, in the apparent position of a heavenly body from which it emanates, arising from its passage through the earth's atmosphere; hence distinguished as atmospheric refraction, or astronomical refraction

The bending of a beam of light through an interface between two dissimilar media or in a medium whose refractive index is a continuous function of position (such as graded-index fiber)

The bending of elecrtomagnetic rays as they pass from one medium to another

The bending of light wave as they pass from one medium to another

The act of refracting, or the state of being refracted

the amount by which a propagating wave is bent

The bending of light as it passes from one medium into another; the amount of bending depends on the speeds of light in the two media

The phenomenon of a beam of light bending as the light's velocity changes This occurs when the refractive index of the material through which the light is passing changes Let i be the normalized incident ray vector (pointing towards the surface), which has unit surface normal n If t is the transmitted (refracted) vector inside a transparent medium, then: where is the ratio of the refractive indices of the inside and outside media (See Snell's law )

The bending of light rays as they pass through a transmission medium of one refractive index into a medium with a different refractive index

The bending of light at a particular angle as it passes through a transparent medium (such as glass or water) Rainbows are causes by light refracting and reflecting (twice) inside raindrops

The change in direction of an electromagnetic wave resulting from changes in the velocity of propagation of the medium through which it passes

When a ray of light passes from one medium to another, the difference in the speed of light in the medium results in an apparent bending of the light at the interface This is known as refraction See the section on specular transmission for details
