alleryThe magnification produced by a thin lens is:
Am = u/v
Bm = v/u
Cm = −v/u
Dm = h/h'
Answer & Solution
Correct answer: B. m = v/u
**Lens magnification: m = h'/h = v/u** (note: positive sign, unlike mirror where m = −v/u).
**For a convex lens forming a real image:** u < 0 and v > 0
→ m < 0 → inverted image.
