    STATEMENT-1 The formula connecting u,v and f for a spherical mirrors whose sizes are very small compared to their radii of curvature. STATEMENT-2 Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.

    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.

    Choose the correct relation between u, v and r for a spherical mirror:
