When an object is placed between the principal focus (F) and twice the focal length (2F) of a convex lens, a real, inverted, and enlarged image is formed beyond 2F on the other side of the lens.

The position and nature of the image formed by a convex lens depend on the object’s position relative to the focal point and 2F.

Placing the object at twice the focal length (2F) produces a real, inverted image of the same size at 2F. Placing the object at infinity produces a real, inverted, diminished image at the focal point (F). Placing the object beyond twice the focal length (beyond 2F) produces a real, inverted, diminished image between F and 2F.
