Concave mirror physics help

  1. Dec 12, 2007 #1
    As the object is moved along the principle axis toward the vertex of a concave mirror, the type of image changes. Where does the change in type of image occur? Explain why, in terms of the path of the light rays.

    I just don't know what it means, can you guys help me with this question?... I would be very gratefull..

    Concave mirrors are capable of producing different types of images. The location (distance from mirror), size (bigger, same, smaller) and orientation (upright or inverted) of the image produced depends on the focal length of the mirror and the position of the original object whose reflection is being viewed.
