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 `(I)/(2)` Now another identical polarizer C is placed between A and B. The intensity beyond B is now found to be `(I)/(8)` . The angle between polarizer A and C is :
