Per NCERT, what is the FORMULA for MAGNIFICATION (m) of a spherical mirror — in terms of image distance v and object distance u?
Am = u/v
Bm = h'/h = v/u (this is for lens)
Cm = f/u
Dm = h'/h = −v/u
Answer & Solution
Correct answer: D. m = h'/h = −v/u
Per NCERT Eq 9.3, mirror magnification m = h'/h = −v/u. Lens magnification is +v/u.
