When the rays of light come from an object placed at infinity then there are two cases , First case when the rays of light fall obliquely to the principal axis and the second when the rays of light are parallel to the principal axis.

In both the cases the image will be formed at the Focus , of the mirror .

• Nature - The image formed is real & inverted.
