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..

The apparent depth of an object lying deeper in an optically denser medium appears to be lesser than its actual depth, due to refraction at a plan surface. This can be seen as follows. ..
