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 1/8 . The angle between polarizer A and C is :
(a) 30º
(b) 45º
(c) 60º
(c) 0º
