Draw the final image formed by two lenses:
An optical imaging system consists of two positive lenses (L1 and L2). L1 has a focal length f1 = 10 cm, and L2 has a focal length f2 = 5 cm. Two lenses are separated by L = 40 cm. An object (denoted by the vertical arrow) with height h is located in front of the first lens with a distance of 15 cm.
(a) In the following diagram, draw the final image formed by these two lenses.
(b) Using the lens equation, please calculate the location of the final image with respect to the center of L2. Also what is the final magnification?
