Two Lens System Given: F i n d : cm h object 5 ? 2 f cm X 75 1 cm f 50 1 cm X 200 2 cm X 200 3 An object 5 cm high is located 75 cm from a converging lens (X 1 = 75 cm) of focal length f 1 = 50 cm. A second converging lens of focal length f 2 is located 200 cm from the first lens (X 2 = 200 cm). An image of the object is to be formed on a screen 200 cm from the second lens (X 3 = 200 cm). What must be the focal length f 2 of the second lens so that the final image appears on the screen? Solutions a.) To find F we can use the following formula: f s s 1 1 1 1 1 1 1 1 f s X 1 1 1 1 f s X X s
