L equal to b of the same parts, b being the denominator of the value of /x.Draw LQ in the second medium normal to the surface to meetthe circle in Q, Join RQ ; then RQ is the refracted ray. The figure has been drawn to represent the case of lightgoing from air to glass, for which p. = 1 5 = 3/2, so… … Fig. 36. To verify this construction we may have recourse to adirect experiment, such as that described in Experiment 10,Section 35. We shall there see that if PR and RQ be anincident and refracted ray, P and Q being the points inwhich they cut respectively a circle with R as centre, and if 56…
