Neco 2021 Physics Question 38
Practice objective / multiple choice question 38 from the 2021 Neco Physics examination.
A converging lens \(L_{1}\) has a focal length of \(12\) cm. An object (a candle) is placed \(18\) cm to the left of \(L_{1}\) and a real image is formed. A second converging lens \(L_{2}\) is positioned \(15\) cm to the right of \(L_{1}\). The image formed by \(L_{1}\) serves as the object for \(L_{2}\). A screen placed \(40\) cm to the right of \(L_{2}\) captures the final image. Determine the focal length of \(L_{2}\) (in cm, to one decimal place).
