Polarized light passes through a polarizer. If the electric vector of the polarized light is horizontal what, in terms of the initial intensity I0,
 
  is the intensity of the light that passes through a polarizer if the polarizer is tilted 22.5 from the horizontal?
  A) 0.191I0 B) 0.854I0 C) 0.147I0 D) 0.011I0
