A thin equiconvex lens of glass of refractive index u=3/2 and of focal length 0.3 m in air is sealed into an opening at one end of tank filled with water (u= 4/3). On the opposite side of the lens, a mirror is placed inside the tank on the tank wall perpendicular to the lens axis as shown in figure-5.272. -0.9m------ -3/2 ANDA Lens -0.8m- -4/3 Mirror Figure 5.272 The separation between the lens and the mirror is 0.8 m. A small object is placed outside the tank in front of the lens at a distance of 0.9 m from the lens along its axis. Find the position (relative to the lens) of image formed by the system.
