The linear magnification produced by a spherical mirror is given by:
Am = u/v
Bm = −v/u (with sign convention)
Cm = v × u
Dm = f/u
Answer & Solution
Correct answer: B. m = −v/u (with sign convention)
**Magnification m = h'/h = −v/u**. Sign of m tells about image orientation: **negative m → inverted image (real); positive m → erect image (virtual)**.
