Transcribed Image Text:

An extended object is placed at point O, 10 cm in front of a convex lens L and a concave lens L is placed 10 cm behind it, as shown in the figure. The radii of curvature of all the curved surfaces in both the lenses are 20 cm. The refractive index of both the lenses is 1.5. The total magnification of this lens system is L L Of (A) 0.4 O 10 cm (B) 0.8 10 cm (C) 1.3 (D) 1.6 An extended object is placed at point O, 10 cm in front of a convex lens L and a concave lens L is placed 10 cm behind it, as shown in the figure.
