(a) Concave
(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.

(a) Concave mirror: Because to get powerful parallel beams of light.
(b) Convex mirror: Because these mirrors are fitted on the sides of the vehicle, enabling the driver to see traffic.
(c) Concave Mirror: Because to get powerful parallel beams of light.

A 10 mm long awl pin is placed vertically in front of a concave mirror. A 5 mm long image of the awl pin is formed at 30 cm in front of the mirror.

(b) – 20 cm is the correct option.

A spherical mirror and a thin spherical lens have each a focal length of −15 cm. The mirror and the lens are likely to be

By convention, the focal length of a concave mirror and a concave lens are taken as negative. Hence, both the spherical mirror and the thin spherical lens are concave in...

A spherical mirror and a lens have same focal length of - 20 cm. What type of mirror and lens are these?

A concave mirror and concave lens have negative focal length. Hence, both mirror and lens are concave.

How can you distinguish between a plane mirror, a concave mirror and a convex mirror without touching them?

By observing the virtual images formed by the three mirrors, we can distinguish between the mirrors as: (i) Plane mirror will produce an image of the same size, (ii) Concave mirror will...
