A split lens has its two parts separated by `a` and its focal length is `f`. An object is placed at a distance `(3f)/(2)` on the axis of undivided lens as shown. The distance between the virtual source is

An object is placed at a distance of f/2 from a convex lens of focal length f. The image will be

An object is placed at a distance f in front of a concave lens of focal length f. Locate its image.

An object is placed at a distance f in front of a concave lens of focal length f. Locate its image.

An object is situated at a distance of f//2 from a convex lens of focal length f Distance of image will be-

A point object is placed on the optic axis of a convex lens of focal length f at a distance of 2f to the left of it. the diameter of the lens is 'd' . An eye is placed at a distance of 3f to the right of the lens and a distance h below the optic axis. The maximum value of h to see the image is
