| Abstract: | In this paper the fourth special ray in construction is presented and demonstrated af-ter analyzing the three special rays. Its physical concepts are clear when this ray is used to make dia-grams and obtain the image.It is as simple as the other three ordinary ones in method and steps and has the same universality. |
