Images Formed by Concave Mirror

The following figures show images formed by a concave mirror. (a) An object is far away, a tiny real image is formed at F. (b) When it is moving from far away towards C, a real, inverted, smaller image is formed moving from F to C. (c) The object and its inverted image meet at C and are the same size. (d) As the object moves from C towards F, a real, inverted, larger image is formed moving from C to far away. (e) When the object arrives at F, the image is at infinity, and cannot be formed. (f) As the object moves from F towards the mirror, a virtual, upright, larger image is formed behind the mirror.
