A medium has an absolute refractive index of √3. What will be the polarising angle for this medium?
-
A.
60°
-
B.
0°
-
C.
45°
-
D.
30°
Correct Answer:
A. 60°
Explanation:
To find the polarizing angle (also known as Brewster's angle), you use Brewster's Law, which states that the tangent of the polarizing angle is equal to the refractive index of the medium. The formula is expressed as tan(?) = n. Given that the refractive index (n) is v3, you can set up the equation as tan(?) = v3. The angle whose tangent value is v3 is 60°. Therefore, the polarizing angle for this medium is 60°.
