Answer 1

Explanation:

Image Formation by Spherical

When a ray, parallel to principal axis strikes concave or convex mirrors, the reflected ray passes through the focus on the principal axis. When a ray, passing through focus strikes concave or convex mirrors, the reflected ray will pass parallel to the principal axis.
