Concave and Convex Lenses - The type of lenses which converge the light beam coming from the source to one point on the other side to form an image is called as a convex lens, while the concave lens which is thinner at the centre and gets thicker as we move towards the edges is called as Concave lens. Concave mirrors are called converging mirrors because as light falls on the mirror, it collects the light and refocuses the parallel incoming rays. Convex mirrors used for security purposes A concave mirror shows different image types depending on the distance between the mirror and the object. Concave mirrors are also used in satellite dishes, electronic microscope, visual bomb detectors, etc. In a reflector telescope, light from the object of interest enters the far end of the telescope and strikes a concave mirror at the end close… Both side-view and rear-view mirrors are convex, which means that the image focal point is actually behind the mirrors and the reflected rays spread outward. Khan Academy is a 501(c)(3) nonprofit organization. Concave mirrors are used in optical instruments such as Ophthalmoscope. Convex mirror & applications (Hindi) Our mission is to provide a free, world-class education to anyone, anywhere. Street Light Reflectors.

This makes the retina visible and makes it easy for doctors to check. Concave mirrors are most commonly used in shaving because of their reflective and curved... Concave mirror uses in the ophthalmoscope. Uses of concave and convex mirror: Concave and convex mirrors used in various dentist tools and for those ENT specialists who want to focus inner parts like throat, ear, and teeth. The concave mirror is used in the solar ovens and the solar furnaces to collect a large amount of solar energy in the focus of the mirror for cooking food, heating water, recharging power … Thanks to the optical properties of convex mirrors, motorists have a buffer against all manner of dangers. Driving a car without being able to know what's going on behind you would be a hazardous endeavor indeed. Satellite dishes for residential television reception are virtually ubiquitous in the 21st century, and they have important commercial and military applications.

The convex mirror used in rear view car mirrors. Ophthalmoscope has a concave mirror that has a hole in the middle. Therefore, they are mostly used to focus light. Convex mirrors are widely used as rear-view mirrors in automobiles and vehicles because it can diverge light beams and make virtual images. Today, two types of telescopes are widely used: refractor telescopes, which employ lenses, and reflector telescopes, which have mirrors.
