A thin bi-convex lens made up of glass of refractive index 3//2 is placed is front of a plane mirror. The space between the lens and the mirror is filled with water of refractive index 4//3 . The radii of curvatures of the lens are R_(1)=15cm and R_(2)=25 cm . A point object is placed at distance x from the surface whose curvature is R_(1) . The distance x is greater than the separation between the lens and the mirror. Find the value of x so that image must coincide with the object.
