Consider a ray of light incident on XY, normally along OA, it passes straight along OAA l . Consider another ray from O (the object) incident at an angle i on XY, along OB. This ray gets refracted and passes along BC. On producing this ray BC backwards, it appears to come from the point I and henc..
