Summary

[edit]
Description
Français : Trajet des rayons réfléchis par un objet, déviés par une lentille convergente et frappant l'œil d'un observateur.

La figure de gauche représente le trajet des rayons. La figure de droite représente une situation ne comprenant qu'un objet seul, sans lentille, et donnant des rayons identiques au final. Le cerveau de l'observateur, et aucun appareil de mesure recevant la lumière à l'endroit de l'observateur, n'est pas capable de faire la différence entre les deux situations.
