Image formation through converging and diverging lens - JEE PDF Download

A diverging lens with magnitude of focal length 25 cm is placed at a distance of 15 cm from a converging lens of magnitude of focal length 20 cm. A beam of parallel light falls on the diverging lens. The final image formed is :
  • a)
    real and at a distance of 40 cm from the divergent lens
  • b)
    real and at a distance of 6 cm from the convergent lens
  • c)
    real and at a distance of 40 cm from convergent lens
  • d)
    none
Correct answer is option 'C'. Can you explain this answer?

Real and at a distance of 40 cm from the convergent lens


As parallel beam incident on diverging lens if forms virtual image at v1 = –25 cm from the diverging lens which works as an object for the converging lens (f = 20 cm)

So for converging lens u = -40 cm, f = 20 cm
therefore final image

V = 40 cm from the converging lens.
