(b) Convex
(c) Concave
Explanation
(a) Concave mirror is used in the headlights of a car. This is because concave mirrors can
produce powerful parallel beam of light when the light source is placed at their principal
focus.
(b) Convex mirror is used in side/rear view mirror of a vehicle. Convex mirrors give a
virtual, erect, and diminished image of the objects placed in front of it. Because of this,
they have a wide field of view. It enables the driver to see most of the traffic behind
him/her.
(c) Concave mirrors are convergent mirrors. That is why they are used to construct solar
furnaces. Concave mirrors converge the light incident on them at a single point known as
principal focus. Hence, they can be used to produce a large amount of heat at that point.
