A collimated beam of light of diameter 2nm is propagating along the x - axis. The beam is to be expanded to a collimated beam of diameter 50nm using a combination of the convex lenses. A lens of focal length of 50nm and another lens with focal length f are to be kept at a distance a between them. The value of F and d respectively are
  • a)
    450nm and 105nm
  • b)
    400nm and 500nm
  • c)
    550nm and 600nm
  • d)
    1250nm and 1300nm
Correct answer is option 'D'. Can you explain this answer?
