NEET Physics Refraction MCQ Question
Which of the following statements about refraction and total internal reflection is correct?
Total internal reflection occurs when the angle of incidence exceeds the critical angle.
Refraction always results in light being transmitted through a medium.
The angle of refraction is always greater than the angle of incidence when light travels from a denser to a rarer medium.
Light can be totally reflected at any angle of incidence.
Correct Answer
Detailed Explanation
Total internal reflection occurs when the angle of incidence exceeds the critical angle, as stated in the NCERT context. In this case, no transmission of light occurs, contradicting options B and C.
