How do you get a virtual image using a concave mirror? (AS1)

When the object is placed between focus and pole, then principal rays are drawn through the object. The first ray is drawn through the center of curvature and the second ray is incident parallel to the principal axis which passes through focus after reflection. Both the reflected rays when produced further does not meet at a point. So, both the reflected rays are produced backward beyond the mirror so as to meet at a point. At this point, we get an image which cannot be obtained on a screen. This image is virtual, erect and enlarged.
