A converging lens of focal length \(f_{1}=0.20\) m forms a real image of a candle placed \(u_{1}=0.50\) m from the lens on a screen. A second converging lens of focal length \(f_{2}=0.10\) m is positioned \(0.05\) m behind the screen to view the image. Determine (i) the distance of the final image from the second lens and state whether it is real or virtual, and (ii) the overall magnification of the two‑lens system.

Answer Options

A. 0.15 m (real, on the image side); overall magnification ≈ -0.75
B. 0.12 m (real, on the image side); overall magnification ≈ -1.00
Correct Answer C. 0.10 m (virtual, on the object side); overall magnification ≈ -1.33
D. 0.08 m (virtual, on the object side); overall magnification ≈ -2.00
Correct Answer
C
Correct Option:
0.10 m (virtual, on the object side); overall magnification ≈ -1.33
