Answer 2

$\huge \fbox \red{❥Answer}$

Image formation by Spherical Mirror are

ii) A ray passing through the principal focus of a concave mirror or a ray which is directed towards the principal focus of a convex mirror, after reflection, will emerge parallel to the principal axis.

iii) A ray passing through the centre of curvature of a concave mirror or directed in the direction of centre of curvature of convex mirror, after reflection, is reflected back along the same path.

iv) A Ray incident obliquely to the principal axis, towards a point P on the concave mirror or a convex mirror is reflected obliquely. The incident and reflected ray follow the law of reflection at the point of incident, making a angles with the principal axis.
