Lenses are incredibly important to us. Headlights Near the base of a microscope, you may find a concave mirror mounted so it can be turned in any direction. As the distance is very large, the waves reaching the earth from the antennas are in parallel. Due to this reason, the parabolic reflector collects those rays which are coming from any distant object and that can do the best job. Plane Mirror Reflections Because a plane mirror is flat, light reflected off if it does not curve inward or outward. W hen the object is between the center of curvature and the focus at a distance more than the focal length but less than the radius of curvature , The image is after the center of curvature at a distance greater than the radius of curvature , The image is real , inverted and enlarged magnified. Instead of shine up the sun to some specimen concave mirror shines on the view from the stars onto a flat mirror.
A convex mirror is used by drivers of automobile as a real view mirror. This means ladies images can be projected on a physical plane. The dentists use concave mirror to observe large images of the teeth of the patient. There are many uses of Concave mirror in daily life as they can also apply for security purposes. The concave mirror is madewith a surface that bends inward.
Light being passed through a concave lens. It consolidates the rays of light that travel through it, as opposed to diverting and spreading them the way a concave lens does. Thanks to the optical properties of convex mirrors, motorists have a buffer against all manner of dangers. In effect, this makes images appear smaller when viewed through a concave lens. A concave mirror is used as doctors head mirrors to focus light on the body parts like eyes, ears, nose, throat etc. Flat mirror were previously used for decorative purposes and also as a looking glass. The focus of concave mirror The focus of the concave mirror is produced due to the collection of the reflected rays emitted from a far object such as , The rays after being reflected collect in one lit point which is called the focus of the mirror that can be received on the screen.
They are the type of lens responsible for magnification and are the most common lens used in photography and other common applications. It is true that the primary lens used in binoculars and telescopes is a convex lens, but concave lenses are also involved. In the study of physics, concave and convex mirrors are often discussed and experimented with — but not nearly as much attention is given to the type of mirrors used every day. As light travels through the lens, it bends either outward or inward, toward the thickest part of the lens. Convex lens and concave lens are used in many things , They are used in the medical eye glasses either for reading or walking , They are used in the wars , the leaders use the binoculars to follow the battles. Thus when these parallel waves strike a concave surfaced mirrored antenna dish, they all get reflected by the focus of the concave mirror. Beth Richards, a freelance writer since 2002, writes about health and draws from her 25 years as a licensed dispensing optician.
The images that are formed inside the mirror are virtual images. Concave lenses, though, serve an important role as well. Convex lenses and concave mirrors form real images. Through this viewer see the reflection on the mirror. Their main task is to converge any sort of rays falling on them.
To view physical appearance by own-self. When these rays pass through the center point of curvature, then the rays reflect itself. A convex mirror is used as a reflector in street lamps. These haters use large concave Mirrors that can Converse the highly energetic solar radiation to a single point producing enormous amount of heat that can be utilized in generation of huge amounts of power which can not only be used for domestic purposes like hitting water and room heating but also can be used to produce steam to run conventional turbines to produce electricity. There are numerous uses of concave mirror in daily life. Convex lenses have a significant drawback when used in optical applications like binoculars and telescopes.

Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays. It is essential to focus the mirror point to collect light from the sun. Concave Mirrors are converging mirror which have depression in the middle as compared to the periphery. Concave mirrors are used by doctors to focus light into ears,throat etc. Since it also helps to catch the details of the face it also is used as mirrors in makeup rooms and makeup kits. Dentists need to examine theminute parts of teeth.
Motor Vehicles Driving a car without being able to know what's going on behind you would be a hazardous endeavor indeed. Concave lenses are used in flashlights to spread out the beam of light so that it covers a much wider area. A concave lens contains at least one inwardly-curved surface, and it is also referred to as a divergent lens. Concave mirrors are used in the and magnifying glasses , They are used in the visual bomb detectors and they are used in the flash light mirror of camera. Because it focuses the solar energy into higher intensity levelswhere it's more useful. They are also used in car light's but is very hard to explain.
Therefore they are mostly used to focus light. The first answer above relates to a concave mirror. They have bulge in the middle. A convex mirror is used as a reflector in street lamps. As a result, light from the lamp diverges over a large area.
