Light refracted through Prism question~~
Here is the problem:
Light is incident along the normal to face AB of a glass prism of refractive index 1.67, as shown in the figure.
Find, "alpha_max" the largest value of the angle "alpha" such that no light is refracted out of the prism at face AC if the prism is immersed in air.
-The diagram is a simple one of a right triangle representing the prism, the topmost corner is labeled A, and B and C are the base corners. Therefore, side AC is the hypotenuse, and Angle "alpha" is located at corner C. Hope all this makes sense! Let me know if it doesn't.
Any help is appreciated!
