Hello Shalini ❤

Great Question

Here's your answer ❤

Centre of curvature : The centre of sphere of which the mirror form a path is called centre of curvature. The area of a convex mirror that is exposed to incident light is called the aperture. If the aperture of a convex mirror is small, then its focal length is equal to half its radius of curvature.

Hope this helped you dear ♥❤
