uses of concave mirror.and convex mirror....and lens also/....
explain all in details

Concave Mirror-:We are familiar that the spherical mirrors are not plane, they are curved in one particular direction. They are curved inward. A concave mirror is also known as the converging mirror as in these type of mirrors light rays converge at a point after they strike and are getting reflecting back from the reflecting surface of the mirror
A concave mirror produces real and inverted images except when the object is placed very near to the mirror that pole (p) and the focus (f) where the image produced is virtual and erect. The concave mirror is used in shaving mirrors to see a large image of the face. It is also useful in vehicle headlights and torches. Dentists also use a concave mirror to get the bigger image of the teeth.
Convex mirror:-
The convex mirror has a reflective surface that curves outward. These mirrors are “always” form virtual, erect and diminished regardless of the distance between the object and mirror.When parallel rays of light strike the mirror, they are reflected in a way wherein they spread out or diverge. For this reason, a convex mirror is also a diverging mirror too. If these reflected rays are extended behind the mirror by dotted lines, they meet at a point. This point is the focus of the convex mirror. The concave mirror is used in the vehicle so that the driver is aware of the vehicle coming from behind. They are also used in street light reflectors.
Explanation:
The concave mirror is a converging mirror so that it is used for many purposes, It is used as a torch to reflect the light, It is used in the aircraft landing at the airports to guide the aeroplanes, It is used in shaving to get an enlarged and erect image of the face.
