refraction
The bending of oblique incident rays as they pass from a medium having one refractive index into a medium with a different refractive index.
refractive index
->
index of refraction
The ratio of the velocity of light in a vacuum to the velocity of light in a refractive material for a given wavelength.
ray tracing
Ray tracing is a rendering technique used in computer graphics to simulate the way light interacts with objects in a scene. It involves tracing the path of rays of light as they travel through a...
Rayleigh interferometer
A device that is used to determine the index of refraction of a gas or liquid through the interference patterns formed by two beams of light, one of which has been transmitted by the sample. A single...
refracted wave
A wave of radiation that has undergone refraction.
refracting sphere
A transparent sphere that has an index of refraction that is different from that of the medium surrounding it; used in optics to demonstrate refraction and astigmatic image formation.
relative dispersion
->
dispersive power
A measure of the dispersive properties of a glass. The relative dispersion is defined as: where C, D, and F refer to the material's index of refraction at the three chief Fraunhofer lines in the...
