Un nuovo approccio all’ottica geometrica che mette in discussione la distinzione corrente tra immagine reale e virtuale

We here propose a new approach to the didactics of the so-called geometrical optics, an approach which is founded on an experimental basis and is useful in pointing out several common misconceptions. The main consequences of such a path are both the discovery of the real images formed by a plane mirror and the revision of the traditional notion of virtual image
