Question

Do we expect any change in the position, nature and size of the image (i) formed by a concave lens, (ii) with a change in the position of the object?

Answer 1

No, the image formed by a concave lens. 

(i) Is always formed between the optical centre and the focus of the lens.

(ii) Is always virtual, erect and diminished in size. This is true for all positions of the object on the principal axis.
