Question

Each question contains statement-1 (assertion) and statement-2 (reason). Of these statements, mark correct choice if Statement-1 : 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-2 : Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.\

(c) : The formula is derived under paraxial approximation. Only those rays are considered which make very small angle with the principal axis. This requires a small aperture. Statement-1 is true. Statement-2 is false, the laws of reflection are valid whenever the light is reflected. Nature of surface does not matter.\
