2. Ray (optics) - Wikipedia

   en.wikipedia.org/wiki/Ray_(optics)

   The principal ray or chief ray (sometimes known as the b ray) in an optical system is the meridional ray that starts at an edge of an object and passes through the center of the aperture stop. [ 5 ] [ 8 ] [ 7 ] The distance between the chief ray (or an extension of it for a virtual image) and the optical axis at an image location defines the ...

3. Light - Wikipedia

   en.wikipedia.org/wiki/Light

   Beam of sun light inside the cavity of Rocca ill'Abissu at Fondachelli-Fantina, Sicily. The speed of light in vacuum is defined to be exactly 299 792 458 m/s (approximately 186,282 miles per second). The fixed value of the speed of light in SI units results from the fact that the metre is now defined in terms of the speed of light.

4. Real image - Wikipedia

   en.wikipedia.org/wiki/Real_image

   A real image is the collection of focus points actually made by converging/diverging rays, while a virtual image is the collection of focus points made by extensions of diverging or converging rays. In other words, a real image is an image which is located in the plane of convergence for the light rays that originate from a given object.

5. Specular highlight - Wikipedia

   en.wikipedia.org/wiki/Specular_highlight

   Specular highlights on a pair of spheres. A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). ). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the

6. Halo (religious iconography) - Wikipedia

   en.wikipedia.org/wiki/Halo_(religious_iconography)

   'little glory'), is a crown of light rays, circle or disk of light [3] that surrounds a person in works of art. The halo occurs in the iconography of many religions to indicate holy or sacred figures, and has at various periods also been used in images of rulers and heroes.

7. Caustic (optics) - Wikipedia

   en.wikipedia.org/wiki/Caustic_(optics)

   The rays refracted by a non-flat surface form caustics where many of them cross. Concentration of light, especially sunlight, can burn.The word caustic, in fact, comes from the Greek καυστός, burnt, via the Latin causticus, burning.

9. Virtual image - Wikipedia

   en.wikipedia.org/wiki/Virtual_image

   A real image is the collection of focus points made by converging rays, while a virtual image is the collection of focus points made by backward extensions of diverging rays. In other words, a virtual image is found by tracing real rays that emerge from an optical device ( lens , mirror , or some combination) backward to perceived or apparent ...
