What are the uses of concave and convex mirrors ?

Explanation

Uses of Concave Mirror. 1. Large sized concave mirrors are used to focus solar energy on an object to be heated. Due to a limited amount of oil and gas, the importance of solar cookers can no longer be ignored.
2. Concave mirrors are used as reflectors in car head-lights, search lights, torches and table lamps.
3. Concave mirrors can be used as a shaving mirror. When the concave mirror is placed at a distance less than its focal length from the face, a magnified erect image is produced. Hence any cut or left over hair can easily be observed with the help of a concave mirror.
4. Concave mirrors are used by doctors to concentrate light on ear, nose, throat, etc.
Uses of Convex Mirror. Convex mirrors are used in automobiles (e.g., scooters, cars, trucks, buses, etc.) to see large traffic at the back. The advantage of using a convex mirror is that it gives a very large field of view of the rear traffic than a plane mirror. The disadvantage of convex mirror is that since the image is always formed between P and F, we cannot accurately judge the distance and speed of the traffic at the back. Usually two mirrors, one plane and the other convex are used to see back traffic. Whereas convex mirrors, on side of vehicle gives wide field of view, plane mirror in front of driver helps us in judging the distance and speed of the back traffic.
