WitrynaTotal internal reflection in the prism. Many optical instruments use right-angled prisms to reflect a beam of light through 90° or 180° (By total internal reflection) such as cameras, binoculars, periscope, and telescope. One of the angles of the right-angled prism is 90°. When a ray of light strikes a face of prism perpendicular, it enters ... The primary mirror of a reflecting telescope is a spherical or parabolic shaped disks of polished reflective metal (speculum metal up to the mid 19th century), or in later telescopes, glass or other material coated with a reflective layer. One of the first known reflecting telescopes, Newton's reflector of 1668, used a 3.3 cm polished metal primary mirror. The next major change was to use silver on glass rather than metal, in the 19th century such was with the Crossley reflector. This w…

Torch Lights: Plane mirrors are used in torch lights and flashlights to display light rays, and they are also utilised in overhead projectors for the same purpose. These torch light uses of plane mirrors are excellent for looking at night and in dimly lit regions.

WitrynaSystems of Plane Mirrors The rules of plane mirrors are used sequentially at each mirror in a system of plane mirrors. Two Parallel Mirrors Two parallel plane mirrors act as a periscope and displace the line of sight. There is no parity change. All image rays are parallel to the corresponding object rays. WitrynaPlane mirrors are used in a reflecting periscope.Two plane mirrors are fixed at the bends of the tube at an angle of 4 5 o with the side of the tube.

WitrynaThe reason behind using this mirror: Concave mirrors reflect light falling on it to a single focal point. So the concave mirror used in solar cookers absorbs all the incident sunlight and reflects it to a single focal point. The radiation at the focal point is very powerful as it contains a lot of concentrated thermal energy. WitrynaPeriscope, Floodlights, Shaving Mirror, Kaleidoscope, Street Lights, Head Lamps of a Car.
