(i) at the centre of curvature of a concave mirror 

(ii) between the pole P and focus F of a concave mirror 

(iii) in front of a convex mirror 

(iv) at 2F of a convex lens 

(v) in front of a concave lens

Answer 1

Nature of image: Real, inverted and same size image is formed at the centre of curvature.

Nature of image: Virtual, enlarged and erect image is formed behind the mirror. 

Nature of image: Virtual, erect and diminished, image is formed behind the mirror.

Nature of image: Real, inverted and size to size, image is formed at 2F on the other side of lens.

Nature of image: Virtual, erect and diminished image is formed between O and F on the same side of object.
