Unformatted text preview: 50. (a) A simple implication of Snell’s law is that θ2 = θ1 when n1 = n2. Since the angle of
incidence is shown in Fig. 33-52(a) to be 30º, then we look for a point in Fig. 33-52(b)
where θ2 = 30º. This seems to occur when n2 = 1.7. By inference, then, n1 = 1.7.
(b) From 1.7sin(60º) = 2.4sin(θ2) we get θ2 = 38°. ...
