the angle between the incident ray and the normal. Our mission is to liberate knowledge. A directed-energy weapon (DEW) is a ranged weapon that damages its target with highly focused energy, including laser, microwaves, and particle beams.Potential applications of this technology include weapons that target personnel, missiles, vehicles, and optical devices.. Disclaimer 4. Uses of plane mirrors. Learn plane mirrors with free interactive flashcards. For example, it has provided information about the Moon’s orbit, and we now know that it is receding from Earth at about 3.8 centimeters (1.5 in) per year. A transporter accident places Captain Kirk's landing party in an alternate universe, where the Enterprise is in the service of a barbarically brutal empire. Plane Mirrors are used when you want to directly reflect an image without any distortions. graph{|x| [-10, 10, -5, 5]} In the graph, the y-axis (vertical) represents the Normal. Plane mirrors are used as looking glass. The images reflected by a plane mirror are known as "virtual images" – but they're different than the simulated digital images you can see on your computer screen or in a video game. Plane mirrors are placed on the inside walls of the shops like jewelry shops. Plane mirrors also have many scientific uses. The idea is similar to that of a dental mirror, but these mirrors are a bit bigger. Angle of Incidence. Mirrors sometimes are placed to cover an entire wall to make a shop, restaurant, or other room appear to be bigger. The use of polished mirrors for reflecting light has been known for thousands of years, and concave mirrors have long been used to form real images of distant objects. They are used in periscopes, for signalling, in kaleidoscopes, to see round dangerous bends, in meters, as mirror tiles, in a sextant, in an overhead projector, an SLR camera, car wing mirrors, in microscopes and as reflecting number plates to mention only some! They have never seen Seinfeld and are deathly scared of wasps. Log in. In most of the measuring instruments, a plane mirror is placed under the scale and pointer. As a result, images from a plane mirror lack the interference seen from concave and convex mirrors. Light reflects from a surface with the angle of reflection (compared to a line drawn perpendicular to the surface, which is called the Normal) equal to the angle of incidence, the angle of the incoming light. Think of a plane mirror as window. Plane mirrors are used as looking glass. The History of Mirrors. Plane mirrors are used to make kaleidoscope, a toy which produces beautiful patterns from colored paper, pieces of glass or small colored beads. Historically, mirrors were simply flat pieces of polished copper , obsidian , brass , or a precious metal. Mirrors are most commonly used for personal grooming, decoration, and architecture. 3. 2. how do draw a plane mirror ray diagram ~draw ray to mirror than normal then same angle reflected ~extend reflected ray behind mirror ~points where rays behind mirror … Copyright. It seems as if mirrors have been around forever in some form or another, but mirrors as we know them today haven't been around that long. For plane mirror the usual mirror formula can be used usual mirror formula involves object distance u image distance v and f -the focal length which is equal to R/2 where R is the radius of curvature. Use of plane mirrors: 1. While the first manmade mirrors were made from intensely polished bronze, silver and other metals, today most mirrors are made from glass sheets finished with a thin layer of aluminum. Uses of Plane Mirrors. A mirror is flat or curved surface usually produced of glass that has had a reflective coating applied to it. shows how light travels. 2. To see any image in the mirror a person should be in the line of sight of the mirror, as when the person is in the line of sight of the mirror then the reflected ray reaches that person’s eye through which anyone can see the image of the object if they are in the line of sight of the mirror, this is because light has the property of moving in a straight line. Mirrors are used while looking for explosives underneath a vehicle. Mirrors are also used in scientific apparatus such as telescopes and lasers, cameras, and industrial machinery. A mirror with a flat surface is a plane mirror: A "standard" mirror without an inward or outward curve. Virtual images are images that are formed in locations where light does not actually reach. 2 C. 3 D. 4 E.
