A convex lens of focal length 'F' produces a real image 'n' times the size of the object. The image distance is

Options

  1. AF ( n +1)
  2. BF ( n -1)
  3. CF ( n +1)
  4. DF ( n -1)

Correct answer

A. F ( n +1)

Step-by-step solution

v u =(-n) v=(-u n) 1 F = 1 v - 1 u v F =1- v u =1+n v=F(1+n)
