Graph of \(\sin\theta_Y\) versus \(\sin\theta_X\) for refraction at the boundary between medium X and medium Y.
Graph of \(\sin\theta_Y\) versus \(\sin\theta_X\) for refraction at the boundary between medium X and medium Y.
A beam of monochromatic light travels through medium X and is incident on the flat boundary with medium Y. A student measures the angle of incidence \(\theta_X\) in medium X and the corresponding angle of refraction \(\theta_Y\) in medium Y, creating the graph of \(\sin\theta_Y\) versus \(\sin\theta_X\) shown. Based on the graph, what is the critical angle for total internal reflection for light traveling in medium X toward the boundary with medium Y?
