Optics refraction
WebJan 6, 2016 · The light that reflects of the bottom half of the pencil travels first through water and then through air. As light crosses the boundary between these two media (plural for medium) it bends. This phenomenon is called refraction. This refraction of light creates the appearance of a bent pencil as shown in the figure. WebRefractive Index is the ratio of the speed of light in a vacuum to the speed of light in the specified material - a description of how light slows down as it passes through an optical material. The refractive index for optical glasses, nd n d , is specified at a wavelength of 587.6nm (Helium d-line).

In medicine, particularly optometry, ophthalmology and orthoptics, refraction (also known as refractometry) is a clinical test in which a phoropter may be used by the appropriate eye care professional to determine the eye's refractive error and the best corrective lenses to be prescribed. See more In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.
