There are two types of spherical
(a) Concave mirrors
(b) Convex mirrors
(a) Uses of Concave Mirrors :
1. A concave mirror is used as shaving or make up mirror because it forms a magnified and erect image of the face when it is held closer to the face.
2. Doctors use concave mirrors as head mirror. The mirror is strapped to the doctor’s forehead and light from a lamp after reflection from the mirror is focussed into the throat or ear of the patient.
3. A small concave mirror with a small hole at its centre is used in the doctor’s Ophthalmoscope. The doctor looks through the hole from behind the mirror while a beam of light from a lamp reflected from it is directed into the pupil of patient’s eye which makes the retina visible.
4. Concave mirrors are used as reflectors in headlights of cars, etc. The source is placed at the focus of a concave mirror. The light rays after reflection travel over a large distance as a parallel intense beam.
(b) Uses of Convex Mirrors :
A convex mirror is used as a rear view mirror in automobiles. The reason is that it always forms a small and erect image and it has a larger field of view than that of a plane mirror of the same size.
