Medium 1 (n1= 1.4) and medium 2 (n2= 2.3) are two rectangular-shaped layers stacked together. An incident ray in medium 2 makes a right triangle with sides AB and BC; AB is along the normal direction to the interface. If the height of AB is h = 368 m, what is the minimum distance of BC (unit in meters) that will result in total internal reflection at the interface? n
