(a) Two converging lenses of focal length F, = 20 cm and F, = 25 cm are placed 90cm apart and an object OA is placed 30 cm in front of the lens L1 as shown in Fig. 3.%3DO F1F1F2F2L1L2Fig. 3Draw ray diagram showing the position and orientation of the image formed by(i)lens L1 alone.(ii) On the same diagram, consider a ray that passes through the tip of the image oflens Li alone and carefully draw where they go after lens L2 has been added.Locate the position and orientation of the image formed by the combination.(iii) Calculate the distance of the final image formed by the combination from the lensL2.
