A thin equiconvex lens made of glass of refractive index 3//2 and of focal length 0.3m in air is sealed into an opening at one end of a tank filled with water (mu=(3)/(2)) . 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. The separation between the lens and mirror is 0.8m. A small object is placed outside the tank in front of the lens at a distance oa 0.9m from the lens along its axis. Find the position (relative to lens) of the image of the object formed by the system.
