Method of image charges. The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see ...
Geometrical optics. Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays:
[2] [3] [4] Huineng is regarded as the founder of the "Sudden Enlightenment" Southern Chan school of Buddhism, which focuses on an immediate and direct attainment of Buddhist enlightenment. The Platform Sutra of the Sixth Patriarch ( 六祖壇經 ), which is said to be a record of his teachings, is a highly influential text in the East Asian ...
The Hale Telescope is a 200-inch (5.1 m), f/ 3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation in 1928, he orchestrated the planning, design, and construction of the observatory, but with the project ending up taking 20 ...
Upside down goggles. Upside down goggles, also known as "invertoscopes" by Russian researchers, [ 1] are optical instruments that invert the image received by the retinas upside down. They are used to study human visual perception, particularly psychological process of building a visual image in the brain. Objects viewed through such a device ...
In geometrical optics, a focus, also called an image point, is a point where light rays originating from a point on the object converge. [ 1] Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by aberrations of the imaging optics.
The term phi phenomenon is used in a narrow sense for an apparent motion that is observed if two nearby optical stimuli are presented in alternation with a relatively high frequency. In contrast to beta movement, seen at lower frequencies, the stimuli themselves do not appear to move. Instead, a diffuse, amorphous shadowlike something seems to ...
Light being refracted by a spherical glass container full of water. Roger Bacon, 13th century. Lens for LSST, a planned sky surveying telescope. The word lens comes from lēns, the Latin name of the lentil (a seed of a lentil plant), because a double-convex lens is lentil-shaped. The lentil also gives its name to a geometric figure.
