alleryThe mirror formula is:
A1/v + 1/u = 1/f
B1/v − 1/u = 1/f
Cv + u = f
Dv − u = f
Answer & Solution
Correct answer: A. 1/v + 1/u = 1/f
1. The mirror formula relates object distance (u), image distance (v), and focal length (f).
2. 1/v + 1/u = 1/f.
3. Applied with the New Cartesian sign convention (distances measured from pole; positive in the direction of incident light).
