Which one of the following statements regarding lenses is not correct?

A concave lens, also known as a diverging lens, always produces a virtual, upright, and diminished image regardless of the object's position. It cannot form a real image because the light rays passing through it diverge and only appear to meet when traced backward. In contrast, a convex (converging) lens is versatile; it can produce real images (when the object is beyond the focal point) and virtual images (when the object is within the focal point). Furthermore, a convex lens can create images that are smaller, equal to, or larger than the object depending on the object's distance from the lens [1]. For instance, when an object is at 2f, the image is real and equal in size [1]. Therefore, the statement claiming a concave lens provides both real and virtual images is incorrect.
