The mirror equation (relating object distance u, image distance v, focal length f) is:
A1/u + 1/v = 1/f
B1/v − 1/u = 1/f
Cv/u = f
Du + v = f
Answer & Solution
Correct answer: A. 1/u + 1/v = 1/f
**Mirror equation: 1/v + 1/u = 1/f** (Cartesian sign convention). All three quantities take signs per the convention. Magnification m = −v/u.
