AIPMT PRELIMS 2002 Physics Total Internal Reflection MCQ Question
Type: MCQ-numerical-Medium-Class 12
For the given incident ray as shown in figure, the condition of total internal reflection of this ray the minimum refractive index of prism will be :-
A
√3 + 1 / 2
B
√2 + 1 / 2
C
√3 / 2
D
√7 / 6
Correct Answer
Option C
Detailed Explanation
Total internal reflection occurs when the angle of incidence is greater than the critical angle. The minimum refractive index can be calculated using Snell's law and the given angle.
