A biconvex lens separates two media of refractive indices 1.3 and  1.7. the refractive index of the lens is 1.5 and the radii of curvature of the two sides of the lens are `r_(1)=10cm` and  `r_(2)=60cm` .  The medium of refractive index 1.3 extends to 78 cm from the lens and that of refractive index 1.7 extends of 34 cm from the lens. A luminous object O is at a distance of 144 cm from the lens. Find the position of the final image from the lens.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_S01_093_Q01.png" width="80%"
