Unpolarized light of intensity I passes through an ideal polarizer A. Another identical polarizer B is placed behind A. The intensity of light beyond B is found to be $\displaystyle \frac{I}{2}$. Now another identical polarizer $\displaystyle C$ is placed between A and B. The intensity beyond B is now found to be $\displaystyle \frac{I}{8}$. The angle between polarizer A and C is :
Official answer
(3)
$\displaystyle 45$°
