NEET Physics Refraction MCQ Question
If a ray of light is incident from a medium with refractive index onto a medium with refractive index such that , which of the following conditions will result in total internal reflection?
The angle of incidence is greater than the critical angle.
The angle of refraction is equal to the critical angle.
The angle of incidence is less than the critical angle.
The angle of incidence is equal to the critical angle.
Correct Answer
Detailed Explanation
Total internal reflection occurs when the angle of incidence exceeds the critical angle, as mentioned in the context describing the transition from a denser to a rarer medium.
