...triangles equal to the given ratio OA : OR. The ratio RA : RM is equal to sinRBA : s'mRBMbut RBA = PR A, the angle which the incident ray makes with the normal...; hence the ratio RA : RM is also given. Now since if we denote the distances of M from A and B by p, p', these distances are connected by the relation... | |
