MCQ
A far sighted man who has lost his spectacles, reads a book by looking through a small hole (3-4 mm) in a sheet of paper. The reason will be
  • A
    Because the hole produces an image of the letters at a longer distance
  • B
     Because in doing so, the focal length of the eye lens is effectively increased
  •  Because in doing so, the focal length of the eye lens is effectively decreased
  • D
     None of these

Answer

Correct option: C.
 Because in doing so, the focal length of the eye lens is effectively decreased
Because in doing so, the focal length of the eye lens is effectively decreased
