Question
A cylindrical tube (μw = 4/3) is closed at its both ends by two silvered plane-convex lens as shown in the figure. Refractive index of lenses L1 and L2 are 2.0 & 1.5 while their radii of curvature are 5 cm & 9 cm respectively. A point object is placed some where at a point O on the axis of cylindrical tube. It is found that the object and image coincides each other.
Options
A.Position of object w.r.t. L1 is 9 cm
B.Position of object w.r.t. L1 is 10 cm
C.Position of object w.r.t. L2 is 9 cm
D.Position of object w.r.t. L2 is 10 cm
