(b) The radius of curvature is double the focal length of a concave mirror.
(c) A ray passing through the focus cuts through the principal axis of a concave mirror after reflection.
(d) When an object is placed between a concave mirror and its focus, the image formed is virtual, erect and larger than the object.
