NEET Physics Refraction MCQ Question
What happens to the light ray when the angle of incidence exceeds the critical angle at the interface between two media?
Total internal reflection occurs.
The light ray is refracted normally.
The light ray is completely absorbed.
The light ray is transmitted partially.
