Two converging lenses are placed such that they are three focal lengths apart. A final image is projected on a screen which is measured to be 82.0 cm to the right of the final lens.
1. If it is known that the two lenses have the same focal length of 24.5cm , where is the initial object located?
2. What is the linear magnification of the lens system?
