• as the object comes closer to the lens, the size of the image increases. after a point , the image becomes larger than the object. The largest image is formed when the object is at the focus
• for objects closer than the focus, the image is virtual, erect and magnified . also the image is on the side of the incident rays. this is the type of image formed when a magnified glass is placed close to an object

the rules for concave mirror is :-

• the image formed by a concave lens for all positions of an object are virtual, erect and smaller than the object
