Gce Model Questions Vol1 2019 Physics Question 36
Practice objective / multiple choice question 36 from the 2019 Gce Model Questions Vol1 Physics examination.
A system of two thin converging lenses is arranged along a common axis. Lens L1 has a focal length of \(+12\ \text{cm}\). Lens L2 has an unknown focal length \(f_2\). The lenses are separated by \(30\ \text{cm}\). An object is placed \(45\ \text{cm}\) to the left of L1. The final image formed by L2 is real and located \(20\ \text{cm}\) to the right of L2. Determine the focal length \(f_2\) of the second lens (sign indicates converging or diverging).
