FOCUS :focus also called an image point, is the point where light rays originating from a point on the object converge..

BUT, when the object is kept beyond the centre of curvature then rays converge between centre of curvature and the point focus. So now that point CAN BE called as the FOCUS.

Q. Will always the rays coming from infinity parallel to the principal axis?

A concave mirror can converge parallel beams of light at one point. But rays originating from the focus after reflection does not always travel parallel to the principal axis.
