The ratio of the speed of an object to the speed of its real image of magnification m of a convex mirror is

Options

  1. A- 1 m^2
  2. Bm^2
  3. C-m
  4. D1 m

Correct answer

A. - 1 m^2

Step-by-step solution

1 u + 1 v = 1 f aligned & - 1 u^2 d u d t - 1 v^2 d v d t =0 & =- 1 u^2 u₀- 1 v^2 v₀=0 u₀ v₀ & =- u^2 v^2 =- 1 m^2 aligned
