Name the type of mirror used in the following situations.
(a) Headlights of a car.
(b) Side/rear-view mirror of a vehicle.
(c) Solar furnace.
Support your answer with reason.
(a) In the headlights of a car Concave mirror is used. This is because concave mirrors converging mirrors that can produce a powerful parallel beam of light when the light source is placed at their principal focus.
(b) The side/rear-view mirror of a vehicle Convex mirror is used.Convex mirrors give a virtual, erect, and diminished image of the objects placed in front of it and they have a wide field of view therefore the driver can see most of the traffic behind.
(c) In Solar furnaces Concave mirrors are used. Concave mirrors are converging mirrors. That is why they are used to construct solar furnaces. It converges the incident light 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.
