When placed between pole and focus, one ray is parallel to principal axis, on reflection it passes through focus, other hits the pole of the concave mirror, it obeys laws of reflection and is reflected back with ∠i=∠r.
The rays of light are diverged by the mirror and they never actually meet, but when a person looks at the rays emerging from the mirror, they appear to meet behind the mirror forming a virtual upright magnified image, hence a virtual image is formed.
