The plane of polarization of this light is parallel to the axis of the first plate and is incident on the second plate. Malus’s law gives the intensity transmitted by the second plate as () ( ) 22 2 21 1 cos cos cos i I θθ =− = . This light is polarized parallel to the axis of the second plate and is incident upon the third plate. A final application of Malus’s law gives the transmitted intensity as ( ) ( ) 2 3 co 2 23 2 12 1 s cos
