Answer:
Assertion(A) : The centre of curvature is not a part of the mirror. It lies outside its reflecting surface.
Reason (R) : The reflecting surface of a spherical mirror forms a part of a sphere. This sphere has a centre.
Both A and R are correct and Reason is the correct explaination of assertion.
But why?
First of all, the centre of curvature lies on the principal Axis outside the mirror. So, it does not lie on the reflecting surface of the mirror.
Again, the mirror has been obtained by cutting a part of a sphere. Hence, the reflecting surface is actually a part of that sphere.
That sphere has a centre and this centre corresponds to the centre of curvature of the mirror.
