Mirror is an optically opaque material which forms images by the phenomenon of reflection. When light ray incident on the mirror it comes back in to the same medium this is known as reflection.Mirrors are generally classified in to three types.
They are 1.Plane mirror 2.Concave mirror 3.Convex mirror.In the plane mirror, the image is virtual, appears lateral inversion. The concave mirror is also called convergent mirror. It forms virtual and real images. It also forms erected and inverted images. The convex mirror diverges the light rays. It forms virtual, diminished images.
In mirrors, the angle of incidence is equal to angle of reflection. According to Fermat’s principle, light selects the path which takes the least time to travel. This was the principle behind why angle of incidence is equal to angle of reflection. Concave mirror are used in making solar cookers. They are used in medical diagnosis by ENTspecialists
