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

Question 2

  B)
 
  that the speed of light in the medium is greater than the speed of light in vacuum.
  C)
 
  that the speed of light in the medium is less than the speed of light in vacuum.
  D)
 
  refraction is not possible.
  E)
