Detailed Solution

The above statement is True.
The rays falling on a concave lens after refraction always diverge. Therefore, in no situation where the direction is kept, a concave lens always forms a virtual image, which is erect and smaller in size than the intention. [216][217][218]Appropriately[219][220], the Concave lens always forms a virtual, erect and diminished image. Whatever the object's position, a concave lens always creates a virtual, erect, and diminished image. The images' locations at infinity, between O and F, and at any other location between infinity and Oare specified.
[221][222][223]As a result, an image can be created that is virtual, upright, and decreased beyond 2F, at [224][225]2F, or between F and 2F. Therefore, all of the requirements are met.[226][227][228]
