Homework Statement


I'm doing a lab, and I plotted a graph for the refractive index I got about 38.3 degrees
and the material I'm working with is a glass block from reading two text books I came to the conclusion my graph might be wrong =/, because the critical angle for glass in air is 42 degrees. So is my graph wrong since I'm like 4 degrees off?
