Question

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 because
STATEMENT-2 : Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.

• A. Statement- 1 is True, Statement- 2 is True; Statement- 2 is a correct explanation for Statement-1
• B. Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1
• C. Statement-1 is True, Statement-2 is False.
• D. Statement-1 is False, Statement-2 is True.

Answer 1

Answer: (C)

All the formulae linked to spherical surfaces are derived based on the assumption that the aperture is very small.
