alleryStart learning →The magnification produced by a spherical mirror is given by
Am = -u/v
Bm = +v/u
Cm = -v/u
Dm = u/v
Answer & Solution
Correct answer: C. m = -v/u
1. Magnification compares image height to object height, m = h_i/h_o.
2. Similar triangles at the pole make this equal to the distance ratio with a sign.
3. The result is m = -v/u, the minus sign encoding inversion.
