Note: sorry for bad drawing

ANSWER:

Definitions

___________

(a)Centre of curvature is the centre of the sphere of which the spherical mirror is a part. 

(a)Centre of curvature is the centre of the sphere of which the spherical mirror is a part. (b) Radius of curvature is the linear distance between the pole and the centre of curvature.
