NEET Physics Optical Instruments MCQ Question
What phenomenon occurs when a beam of light strikes the water surface at a specific angle, resulting in it being completely reflected back into the water?
Total internal reflection
Partial reflection
Refraction
Dispersion
Correct Answer
Detailed Explanation
Total internal reflection occurs when the angle of incidence exceeds the critical angle, causing the light to be reflected back into the water without any refraction into the air.
