Discuss the position and nature of the image formed by a concave mirror when the object is moved from infinity towards the pole of the mirror.

(N/A) When an object is moved from infinity towards the pole of a concave mirror,the image shifts from the focus to infinity and then behind the mirror.
$1$. At infinity: The image is formed at the principal focus $(F)$,real,inverted,and highly diminished.
$2$. Beyond the centre of curvature $(C)$: The image is formed between $F$ and $C$,real,inverted,and diminished.
$3$. At $C$: The image is formed at $C$,real,inverted,and of the same size as the object.
$4$. Between $C$ and $F$: The image is formed beyond $C$,real,inverted,and magnified.
$5$. At $F$: The image is formed at infinity,real,inverted,and highly magnified.
$6$. Between $F$ and the pole $(P)$: The image is formed behind the mirror,virtual,erect,and magnified.
