NEET Physics Lenses MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which of the following statements about the behavior of light at the interface of different media is correct?

A

Total internal reflection occurs when light travels from a denser to a rarer medium at an angle greater than the critical angle.

B

Refraction always increases the speed of light when moving from one medium to another.

C

Partial reflection and refraction occur simultaneously when light strikes the surface of a denser medium.

D

The angle of incidence is always equal to the angle of refraction at the boundary of two media.

Correct Answer

Option A

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.
