A converging lens (or convex lens) produces a virtual image only when the object is placed closer than its focal length (f) from the lens. This is because, in such a case, the light rays diverge after passing through the lens, and the lens is unable to converge them to form a real image. Instead, the diverging rays appear to emanate from a point behind the lens, forming a virtual image.
