When the object is between F1 and 2 F1
Let AB be an object place on the principal axis of concave lens at a point between F1 and 2F1 . Now from the point A of the object array incident parallel to the principal Axis after reflecting from the lens passed through its second focus F2 as the DA. Dadar incident towords the optical centre O'.
The two reflected ray meet at point a when it is real image of the point A of the object . similarly for the point P of the object the image is at B ' does A' and B' is the real inverted and magnified image of the AB.
____________________________
Characteristics of image :-
The image is beyond 2F2 on the other side of the lens .
The image real and inverted .
The image is magnified .
