In each of the questions, assertion(A) is given by corresponding statement of reason (R) of the statemens. Mark the correct answer. Q. Statement I: The formula connecting u,v and f for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. Statement II: Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.

Assertion The formula connecting u, v and f for a spherical mirror is valid only for mirrors sizes which are very small compared to their radii of curvature. Reason Laws of reflection are stricity valid for plane surface, but not for large spherical.

Assertion:- The formula ((1)/(4)+(1)/(u)=(1)/(f)) connecting u and v for a spherical mirror is valid only for mirros whose sizes are very small compared to their radii of curvatures. Reason:- Laws of reflection are strictly valid for smaller size of of optical system.

Statement I : Focal length of a spherical mirror depends on the distances of object and image from the mirror. Statement II : (1)/(f ) = (1)/(v ) + (1)/(u)
