Expert Answer:

Concave mirror

Convex mirror

A spherical mirror whose reflecting surface is curved inwards is called a concave mirror.

A spherical mirror whose reflecting surface is curved outwards is called a convex mirror.

 

 

A parallel beam of light falling on this mirror converges at a point after reflection.

A parallel beam of light falling on this mirror appears to diverge from a point after reflection.

It is also called a converging mirror.

It is also called a diverging mirror.

It has a real focus.

It has a virtual focus.

The magnification of a concave mirror can be greater, equal or less than 1.

The magnification of a convex mirror is always less than 1.

These mirrors are used as reflectors in projectors, light-house headlights, searchlights, etc.

These mirrors are used as rear-view mirrors in cars and motorcycles, as they enable the driver/rider to view the road and vehicles behind.
