i) at the centre of curvature of a concave mirror.
ii) between the pole P and focas 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

1) image is form at centre of curvature

nature of image : real inverted and same size of object

2) image formed behind the mirror

nature of image : virtual erect and enlarge

3) image formed between pole and focus

nature of image is virtual erect and diminished

4) image form at 2F2

nature of image : real inverted and same size of object

5) image form between pole and focus

nature of image : virtual erect diminished
