STANDARD Physics Polarization MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The velocity of light in air is 3 × 10⁸ m s⁻¹ and that in water is 2.2 × 10⁸ m s⁻¹. The polarising angle of incidence is
A
45.37°
B
50°
C
53.67°
D
63.1°
Correct Answer
Option C
Detailed Explanation
The refractive index n = c/v = 3/2.2. Using Brewster's law, tan iₚ = n, iₚ = tan⁻¹(3/2.2) ≈ 53.67°.
