A concave mirror, or converging mirror, has a reflecting surface that is recessed inward (away from the incident light). Concave mirrors reflect light inward to one focal point. They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror.

What I want to be reviewed is: 1- is the resolution okay 2- is it considered wikipedia's bets work or pleasuring to the eye .. and therefore, should it be nominated as a featured picture or not. Author: Myself User:Eshcorp. Pages they appear in: Curved mirror, but more could be added. Nominate and support. - Eshcorp 07:43, 19 August 2006 (UTC)
The thousands of tiny mirrors are angled to create a surface that curves and bends in different directions. The curves direct rays from an object across the mirror's face before sending them back to the viewer, flipping the conventional mirror image. [1] A patent for a non-reversing mirror was issued to John Joseph Hooker in 1887. [2]
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
There are statements about reflected light illumination using a concave mirror, such as: "The first arrangement of this kind was the Lieberkühn mirror from 1738." [ 18 ] In contrast, a book from 1988 states: "J.N. Lieberkühn introduced the concave mirror named after him for reflected light illumination in 1738, as it was used in similar form ...
The scientists calculated that a huge reflector, made of metallic sodium and with an area of 9 square kilometres (900 ha; 3.5 sq mi), could produce enough focused heat to make an ocean boil or burn a city. [1] After being questioned by American officers, the Germans claimed that the sun gun could be completed within 50 or 100 years. [1] [2]
