Answer:
When a ray passes through focus and incident on a concave mirror then it will travel parallel to principal axis after reflection. Hence the image is formed at infinity.
the object is placed between focus and centre of curvature, the image forms beyond centre of curvature. If the object is placed at principal focus the image forms at infinity. If the object is placed between the pole and the principal focus, the image forms behind the mirror.
