In the case of image formation by a concave lens , what can you say about the position, nature and size of the image relative to the size of the object ?

Explanation

Image formation by a concave lens :
(1) If the object is at infinity , the image is formed at the focus of the lens, on the same side of the lens as the object. It is virtual , erect and much smaller than the object (point image).
(2) If the object is at any finite distance from the lens, the image is formed on teh same side of the lens as the object and between the focus and the optical centre of the lens . It is virtual, erect and smaller than the object . The image distance is less than the object distance.
