Home > Ray (geometry)

In Euclidean geometry, a ray, or half-line, given two distinct points A (the origin) and B on the ray, is set of points C on the line containing points A and B such that A is not strictly between C and B. O----O-----*---> A B C

In geometric optics a ray is a curve describing the direction in which light or other electromagnetic radiation is propagated. The ray in geometric optics is perpendicular to the wavefront in physical optics .

In most simple cases, light rays within a given medium are straight lines. Light passing from one medium to another undergoes refraction or total internal reflection following Snell's law.

Raymond ChandlerRaymond Thornton Chandler ( July 23, 1888 March 26, 1959) was an American author of crime stories and novels. His influence on modern crime fiction has been immense, particularly in the writing style and attitudes that much of the field has adopted over tRaymond KurzweilRaymond Kurzweil (born February 12, 1948) is a pioneer in the fields of optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic musical keyboards. He is author of The Age of Intelligent Machines The AgeRay tracingRay tracing is one of the most popular methods used in 3D computer graphics to render an image. It works by tracing the path taken by a ray of light through the scene, and calculating reflection, refraction, or absorption of the ray whenever it intersects
Rayleigh scatteringRayleigh scattering (named after Lord Rayleigh) is the scattering of light by particles smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases.
