Spherical mirror formula relating an object distance ' u ' image distance ' v ' and focal length of mirror ' f ' may be applied to a plane mirror when

Options

  1. Afocal length goes to infinity.
  2. Bfocal length goes to zero.
  3. Cimage distance goes to zero.
  4. Dimage distance goes to infinity.

Correct answer

A. focal length goes to infinity.

Step-by-step solution

Bymirror formulae 1 ~V + 1 u = 1 f In Plane mirror | V |=| u | 1 | ~V | = 1 |u| to satisfy this condition 1 f =0 f
