NEET Physics Optical Instruments MCQ Question
What is the relationship between the refractive indices of two media when n21 is the refractive index of medium 2 with respect to medium 1?
n12 = 1/n21
n12 = n21 + 1
n12 = n21
n12 = n21 - 1
Correct Answer
Detailed Explanation
The relationship between the refractive indices of two media is given by the equation n12 = 1/n21, which shows how they are inversely related, as mentioned in the NCERT context.
