               Uses of Concave mirror

               A concave mirror which is also called as converging mirror has its reflecting surface

               bulging inwards, i.e. away from the incident light. There are numerous uses of
               concave mirror in daily life. It is used in the aircraft landing to guide the airplanes, it is

               used as a torch to reflect the light rays, it is used during shaving to get an erect and
               enlarged image of the face, etc.







               Some concave mirror uses are listed in the points below.


                     Shaving mirrors

                     Head mirrors

                     Ophthalmoscope


                     Astronomical telescopes
                     Headlights


                     Solar furnaces
