Question

STATEMENT-1: The formula connecting $u, v$ and $f$ for a spherical mirror is valid for 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. [2007]

The formula connecting $u, v$ and $f$ for a spherical mirror $\frac{1}{u} + \frac{1}{v} = \frac{1}{f}$ is valid only for mirrors of small apertures, where the size of the aperture is very small as compared to the radius of curvature of the mirror.

Laws of reflection are valid for plane as well as large spherical surfaces. The laws of reflection are valid whenever the light is reflected.
