Refraction

Refraction is the change in direction of a wave due to a change in its transmission medium. ==Explanation== In optics, refraction is a phenomenon that often occurs when waves travel from a medium with a given refractive index to a medium with another at an oblique angle. At the boundary between the media, the wave`s phase velocity is altered, usu....

Refraction

[metallurgy] In metallurgy, refraction is a property of metals that indicates their ability to withstand heat.{cn|date=June 2013} Metals with a high degree of refraction are referred to as refractory. These metals derive their high melting points from their strong intermolecular forces. Large quantities of energy are required to overcome in...

refraction

1) a process in which a wave, which meets a surface separating two different media, gives rise, beyond the surface, to a wave interpretable by geometrical optics, called a refracted wave 2) the propagation of a wave, interpretable by geometrical optics, called a refracted wave in a medium with properties varying continuously in space

Refraction

All waves can be refracted. Refraction means bending. Light rays refract when they pass through a medium of different density (e.g. when light travels from air into glass). When light passes into a region of increased density (e.g. air to glass) it bends towards the normal. When light passes into a region of reduced density, it bends away from the ...
