Detailed Solution

The above statement is False.
When a ray of light comes from the infinite and strikes the surface of the lens, and then it appears to pass through the focus of the lens, then this type of lens is known as a concave lens. E.g.:The kind of lens a camera uses determines the kind of images it produces. A concave lens or mirror typically produces an image that is inverted and smaller than the actual object.
The corrected statement would be that a concave lens always forms a virtual, erect and diminished image of the object.
