Refraction Problem: Is Halliday Fundamental Physics book wrong, or am I misunderstanding the concept?
Post Body

View the Halliday problem here: https://postimg.cc/ctLr09fN, where the answer in the back of the book is (a), but I'm pretty sure the answer would be (P) — the red lines and P are my addition.
