JEE MainPhysicsGeometrical OpticsMCQ+4 / −1
A diverging lens with magnitude of focal length 25 cm is placed at a distance of 15cm from a converging lens of magnitude of focal length 20cm. A beam of parallel light falls on the diverging lens. The final image formed is:
  1. A
    real and at a distance of 6 cm from the convergent lens.
  2. B
    real and at a distance of 40 cm from convergent lens.
  3. C
    virtual and at a distance of 40 cm from convergent lens.
  4. D
    real and at a distance of 40 cm from the divergent lens.
