The bending of light as it passes between materials of different refractive index.
The deflection or bending of electromagnetic waves when they pass from one kind of transparent medium into another.

The process by which the direction of a wave moving in shallow water at an angle to the bottom contours is changed. The part of the wave moving shoreward in shallower water travels more slowly than that portion in deeper water, causing the wave to turn or bend to become parallel to the contours. See Figure 13.Found on http://www.ecy.wa.gov/programs/sea/swces/products/glossary.htm

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 ...Found on http://www.users.zetnet.co.uk/computing/MainPage/SecDepts/Physics/Resources
The bending of light that occurs at the interface between two transparent media. It occurs when the speed of light changes. See also: Diffraction, Diffuse Reflection, Refractive Index.Found on http://www.diracdelta.co.uk/science/source/r/e/refraction/source.html

Refraction: In ophthalmology, the bending of light that takes place within the human eye. Refractive errors include nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Lenses can be used to control the amount of refraction, correcting those errors.Found on http://www.medterms.com/script/main/art.asp?articlekey=5273
