An object is placed in front of f1 at a distance of O1 = 8 cm on the axis of the lens combination. What is the nature and distance from f2 of the final image ?

Two thin doubled convex lenses of focal length f1 = 24, f2 = 11 cm are placed a part by a distance of 10 cm. An object is placed in front of f1 at a distance of O1 = 8 cm on the axis of the lens combination. What is the nature and distance from f2 of the final image ?

The focal length of a convex lens is 10cm and its refractive index is 1.5 is placed in liquid of refractive index 1.25 then its focal length will be Two thin doubled convex lenses of focal length f1 = 24
