NEET Physics Optical Instruments MCQ Question
What phenomenon occurs when the angle of incidence exceeds the critical angle in a denser medium?
Total internal reflection
Partial reflection
Refraction
Total reflection
Correct Answer
Detailed Explanation
When the angle of incidence is greater than the critical angle, total internal reflection occurs, as stated in the summary of reflection and refraction. This is a key principle in optics, particularly in phenomena like mirages and optical fibers.
