NEET Physics Lenses MCQ Question
Which of the following statements about the behavior of light at the interface of different media is correct?
Total internal reflection occurs when light travels from a denser to a rarer medium at an angle greater than the critical angle.
Refraction always increases the speed of light when moving from one medium to another.
Partial reflection and refraction occur simultaneously when light strikes the surface of a denser medium.
The angle of incidence is always equal to the angle of refraction at the boundary of two media.
Correct Answer
Detailed Explanation
Total internal reflection happens when light moves from a denser medium to a rarer one at angles greater than the critical angle, leading to no refraction occurring, as described in the discussion of total internal reflection.
