Unpolarized light of intensity II   passes through an ideal polarizer A. Another identical polarizer B is placed behind A. The intensity of light beyond B is found to be 12I\frac{1}{2}I   (initial state). Now another identical polarizer C is placed between A and B. The intensity beyond B is now found to be 18I\frac{1}{8}I  . The angle between polarizer A and C is:

  • A.4545^{\circ}Correct
  • B.6060^{\circ}
  • C.00^{\circ}
  • D.3030^{\circ}
