NEET Physics Prism MCQ Question
A prism has an angle of 30 degrees and the minimum angle of deviation is found to be 40 degrees. What is the refractive index of the material of the prism?
50
60
52
62
Correct Answer
Detailed Explanation
Using the formula for refractive index n = sin[(A + D_m)/2] / sin(A/2), we substitute A = 30 degrees and D_m = 40 degrees to get n ≈ 1.52.
