Question
The critical angle for glass is 41°. Light travelling into glass from air has an angle of incidence of 38°. After contacting the surface, the light
Correct Answer
Option A is the correct answer.
Detailed Explanation
When light travels from a rarer medium (air) to a denser medium (glass), it bends towards the normal. Total internal reflection only occurs when going from denser to rarer. Since the critical angle is for glass to air, and light is going from air to glass, it will be refracted (and some reflected).
Hint
Total internal reflection occurs when light travels from a denser to a rarer medium at an angle greater than the critical angle.
