Question

where we use concave and convex mirrors? ​

Answer 1

They are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror. These mirrors are called "converging mirrors" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus.

Answer 2

Since convex mirrors have a wider view field than concave mirrors and plane mirrors, they are mostly used inside mirrors of automobiles.

Convex mirrors used for security purposes.
