NEET Physics Optical Instruments MCQ Question
Which of the following combinations about the behavior of light in different media is correct?
A denser medium has a higher optical density, and light bends towards the normal when entering a denser medium.
Optical density and mass density are the same, and light bends away from the normal when entering a rarer medium.
When light travels from a rarer medium to a denser medium, it always bends away from the normal.
The refractive index of a medium is always greater than 1, and it is defined as the ratio of the speed of light in two media.
Correct Answer
Detailed Explanation
Statement A is correct as it states that a denser medium has a higher optical density and light does indeed bend towards the normal when entering a denser medium. This aligns with the NCERT context discussing optical density and behavior at the interface of different media.
