Neco 2020 Physics Question 32
Practice objective / multiple choice question 32 from the 2020 Neco Physics examination.
Two thin converging lenses are placed coaxially. The first lens has a focal length of \(12\ \text{cm}\) and an object is placed \(18\ \text{cm}\) to its left. The image formed by the first lens acts as the object for the second lens, which is \(8\ \text{cm}\) to the right of the first lens. The final image is formed \(30\ \text{cm}\) to the right of the second lens and is inverted relative to the original object. Find the focal length of the second lens (to the nearest 0.1 \(\text{cm}\)).
