Problem
During a laboratory investigation, students measured the angles of a laser beam as it passed from air into an unknown transparent solid. Their data are shown below.
Trial 1: incident angle 30∘, refracted angle 19∘
Trial 2: incident angle 45∘, refracted angle 28∘
Using these data, the students compared their result with the indices of refraction for several candidate materials listed below.
Material W: fused quartz (n=1.46)
Material X: acrylic (n=1.49)
Material Y: crown glass (n=1.52)
Material Z: flint glass (n=1.62)
Which material is most consistent with the measurements?
(a) Material Z
(b) Material W
(c) Material Y
(d) Material X
