EK no 936 (1000 questions physics) states "light will bend away from normal when entering air and toward the normal when exiting air. The blue light (higher frequency) will bend more at each interface...but then they show the blue light on top of the red light, shouldn't blue/violet light bend more towards the normal when entering glass from air and then away from normal when entering air from glass? I get that blue light has a higher n because of chromatic dispersion, but this question answer shows the exact opposite of what it should be? just wanted to make sure i'm not going crazy. thanks!
