Cylinder Q.25 The figure shows a very long circular cylinder of radius R made of glass u= 3/2 fixed to the horizontal surface. The space between the cylinder and a vertical wall (plane mirror) is filled with water of refractive index 4/3, as shown in figure. Find the positions ofthe final image formed of an object Oplaced on the horizontal axis passing through the centre of mass C of the cylinder. as shown in figure. Express you answer with respect to centre C of the cylinder. Consider only paraxial rays lying in the vertical plane containing the point O and C.
