A light ray travels in water (n=1.33), strikes a glass layer (n=1.50) at an angle of incidence 50∘ and then attempts to emerge into air on the far side. What happens at the glass–air boundary?
a) It emerges making an angle 65∘ with the normal.
b) It suffers total internal reflection inside the glass and does not emerge.
c) It emerges making an angle 27∘ with the normal.
d) It emerges with the same 50∘ angle as in water.
