NEET Physics Optical Instruments MCQ Question
What phenomenon occurs when the angle of incidence is greater than the critical angle in a denser medium?
Total internal reflection
Partial reflection
Refraction into air
Scattering of light
Correct Answer
Detailed Explanation
When the angle of incidence exceeds the critical angle, the light does not refract but is completely reflected back into the denser medium, which is known as total internal reflection.
