🤓 Based on our data, we think this question is relevant for Professor Rolf's class at UN OMAHA.

# Solution: A ray of light traveling in a block of glass (n = 1.52) is incident on the top surface of the block at an angle of 62.8° with respect to the normal. If a layer of oil is placed on the top surface of the glass, the ray is totally reflected. What is the maximum possible index of refraction of the oil?
