A real valued function f : A to B or simply a real function 'f ' is a rule which associates to each possible real number x A, a unique real number f(x) B, when A and B are subsets of R, the set of real numbers. In other words, functions whose domai..

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..
