Unpolarised 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 (implying the axes of A and B are parallel). 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 the transmission axes of polarizers A and C is:
