Question

In this problem like in 8.11, shouldn't one component of thelight be completely absorbed while 50% of the orthogonalcomponent is also absorbed leaving only 1/4 of the original fluxdensity. I solved it as I() = 200W/m2cos2(60)(0.50).
                         so I() = 25W/m2 Why is this at odds with the provided solution?

Explanation / Answer

Given : I ( ) = I ( 0 ) cos2 [ Malus law ]    Hwere I ( 0 ) is irradiance arriving onthe analyzer or second ideal linear polarizer I ( 0 ) = 200 W/m2 Angle ( ) = 30o Angle ( ) = 30o    I = ( 200 ) ( 0.87 )2       = 151 W/m2 I hope it helps you I hope it helps you
