  2. Curved mirror - Wikipedia

    en.wikipedia.org/wiki/Curved_mirror

    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.

    en.wikipedia.org/wiki/Hockney–Falco_thesis

    In July 2000, Falco and Hockney published "Optical Insights into Renaissance Art" in Optics & Photonics News, vol. 11, a detailed analysis of the likely use of concave mirrors in certain Renaissance paintings, particularly the Lotto painting. Experiments with a concave mirror (which technically is also a lens) of the calculated properties ...

    Uses Head Mirror with head band: to focus light into the cavity under inspection; mirror is concave and is used with a Chiron lamp to produce a parallel beam of light; doctor views through the hole (average diameter of mirror is 3 & 1/2" & that of hole is 1/4") Head mounted lights with head band: to focus light into the cavity under inspection

    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 appear upside down and mirrored. They are constructed using sets of optical right-angle prisms, concave mirrors, or a mirror plus right-angle prisms with unequal cathethus.

    en.wikipedia.org/wiki/Catadioptric_system

    Mangin mirrors were used in searchlights, where they produced a nearly true parallel beam. Many Catadioptric telescopes use negative lenses with a reflective coating on the backside that are referred to as “Mangin mirrors”, although they are not single-element objectives like the original Mangin, and some even predate Mangin's invention.

    This requires the use of the extra-virgin olive oil that you use for daily cooking. Before you ask, no—the eggs do not taste like olive oil. They taste more like eggs, without the dulling effect ...

  8. Real image - Wikipedia

    en.wikipedia.org/wiki/Real_image

    Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. As the object approaches the focal point the image approaches infinity, and when the object passes the focal point the image becomes virtual and is not ...
