Part C - What happens to the light incident to the normal of the interface at an angle greater than the critical angle?

Explanation / Answer

Part B

Option c, sin^-1(3/4)

Part C

Option d, Above the critical angle, the phenomenon is called Total Internal Reflection (TIR). 100% of the light is reflected. No light transmitted means that there is no viable propagating solution to the Helmholtz equation in the exiting medium
