Concave mirrors are used for various purpose:-1) A concave mirror is used as a reflector in torches, search lights, head lights of motor vehicles etc. to get powerful parallel beam of light. 2. A concave mirror is used as doctors head mirrors to focus light on the body parts like eyes, ears, nose, throat etc., to be examined. 3. A concave mirror is also used as a shaving mirror/makeup mirror, as it can form erect and magnified image of the face. 4. The dentists use concave mirror to observe large images of the teeth of the patient. 5. Large concave mirrors are used to concentrate sunlight to produce heat in solar cookers, solar furnace etc. 6. Large concave mirrors are also used in reflecting type telescope.Convex mirrors are used for various purposes:- 1. A convex mirror is used as a reflector in street lamps. As a result, light from the lamp diverges over a large area. 2. A convex mirror is used by drivers of automobile as a real view mirror. These mirrors are fitted on the sides of the vehicles enabling the driver to see traffic behind for safe driving. This is because (i) A convex mirror produced an erect image of the object. (ii) Size of image formed by convex mirror is much smaller than the object. (iii) Convex mirrors have a wider field of view as they are curved outwards. Therefore, convex mirrors enable the driver to view much larger area than would be possible with a plane mirrorconvex mirrors are used as rear view mirrors of vehicles,used as security mirrors in shops,used as mirrors near signals.A concave mirror is used as dentist mirrors,shaving mirrors,magnifying glass,used in torches
