A concave mirror is made by coating the inner surface of a segment of a spherical shell with a reflecting material. An object with height 1.5 cm is placed on the axis and at a distance of 13 cm from the center of this mirror. The image of this object is inverted and has a height of magnitude 2.5 cm.
If the object is now moved along the axis to a great distance (essentially an infinite distance) from the mirror, where is the image now formed?
