Question
A ray of light traveling through a flat piece of glass arrives at a boundary with air at an angle of 90∘ relative to the surface. What happens to the angle as the light ray moves into air?
Answer
-
It decreases as the ray moves closer to the normal line.
-
It increases as the ray moves farther from the normal line.
-
It does not change because the ray is changing media on the normal line.
-
It does not change because glass and air affect the ray the same.
