1. The index of refraction for water is 1.33 and that of glass is 1.50.
a. What is the critical angle for a glass-water interface?
b. In which medium is the light ray incident for total internal reflection?
The Attempt at a Solution
a. I think the answer to a. is 62.46 degrees, but I am not sure.
b. I think the answer is glass, simply because it is going to be moving from a less dense area to a more dense area.
