Neco 2019 Physics Question 38
Practice objective / multiple choice question 38 from the 2019 Neco Physics examination.
Two converging lenses are placed coaxially. Lens \(L_{1}\) has focal length \(f_{1}=10\,\text{cm}\) and lens \(L_{2}\) has focal length \(f_{2}=20\,\text{cm}\). The separation between the lenses is \(30\,\text{cm}\). An object is placed \(15\,\text{cm}\) to the left of \(L_{1}\). Determine (a) the position of the final image measured from \(L_{2}\) (positive to the right), (b) whether the final image is real or virtual, and (c) the overall magnification of the system (state the sign).
