1.	؟Prove that radius of curvature of concave mirror of small operture is doubled to its focal lengthرا
Answer» EXPLANATION: For spherical mirrors of SMALL apertures, the RADIUS of curvature is FOUND to be equal to twice the focal length. We put this as R=2f. This implies that the principal focus of a spherical mirror lies midway between the pole and centre of *curvature*.

Answer»

For spherical mirrors of SMALL apertures, the RADIUS of curvature is FOUND to be equal to twice the focal length. We put this as R=2f.

This implies that the principal focus of a spherical mirror lies midway between the pole and centre of curvature.
