Give one use of each of a concave mirror and convex mirror.

Hint: Concave means rounded or hollowed; they are also known as converging mirror while convex means curved like and they are also known as a diverging mirror.

Complete step-by-step solution:
A mirror is a surface, which reflects a clear image which is mainly of two types: real image and virtual image, the real image is the one which can be formed on the screen and the one which cannot be formed on the screen is known as a virtual image.
There can be two types of mirror: Curved mirror and plane mirror when a curved mirror is a part of a sphere then it is known as a spherical mirror.
Spherical mirrors are of two types: Concave mirror and convex mirror.
Concave mirrors are spherical mirrors whose inner side is reflecting its focus and center of curvature lies in front of the mirror and convex mirrors are spherical mirrors whose outer side is reflecting whose focus and center of curvature lies behind the mirror.
Use of concave mirror:
A concave mirror is used as a reflector in a torch, searchlights, headlights of vehicles to send parallel rays to infinity so as to get a powered beam of light.

Use of convex mirror:
A convex mirror is used by drivers in automobiles as a rearview mirror because the convex mirror provides a wider field of view than a plane or concave mirror.


Note: Images formed by the concave mirror can be both virtual and erect depending upon the position of an object and image formed by a convex mirror is always virtual and the magnification produced by the concave mirror can be less than or equal to or greater than one and the magnification produced by the convex mirror can be less than one.
