A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in ...
Dual-contour side mirror. Large inboard convex surface is separated from small outboard aspheric surface. A side-view mirror (or side mirror ), also known as a door mirror and often (in the UK) called a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of ...
The work was painted on a specially-prepared convex panel in order to mimic the curve of the mirror used. See also. Self-portrait; Self-Portrait in a Convex Mirror by John Ashbery: the portrait is the subject of a long poem in a poetry collection by Ashbery, both the poem and the collection of the same name. The book won all three of the major ...
Focal length. The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a ...
As in the Cassegrain telescope, the light falls on a concave primary mirror, then is reflected towards a convex secondary mirror. A comparatively small tertiary flat mirror reflects the light to one of the sides of the telescope. (The central hole in the primary mirror may still host a Cassegrain focus if the tertiary can be moved out of the way.)
Plane mirror. A plane mirror showing the virtual image of an urn nearby. A diagram of an object in two plane mirrors that formed an angle bigger than 90 degrees, causing the object to have three reflections. A plane mirror is a mirror with a flat ( planar) reflective surface. [1] [2] For light rays striking a plane mirror, the angle of ...
