Given that, incident intensity, I0=37 W/m2
A)Transmitted angle is, theta=900
then the transmitted wave intensity is, I=I0cos2(theta)
from second polariser so, IA=0.5*I0*cos2(theta)
IA=(0.5)*(37 W/m2)*(cos2(900))
=0
B)
from second polariser so,IB=0.5*I0*cos2(theta)
IB=(0.5)*(37 W/m2)*(cos2(00))
=18.5 W/m2
C)
from second polariser so, Ic=0.5*I0*cos2(theta)
Ic=(0.5)*(37 W/m2)*(cos2(450))
=9.25 W/m2
