Incident light<br />
S 0 = S 0,polar + S 0,unpolar<br />
Transmitted light<br />
S = S polar + S unpolar<br />
a) Minimum transmitted intensity S = S min = 2.0 W/m 2 at θ = 20.0 o .<br />
S is minimum when S polar = 0 since S unpolar is not effected by θ.<br />
S unpolar = S min - S polar = 2.0 - 0 = 2.0 W/m 2<br />
S unpolar = ½ S 0,unpolar è S 0,unpolar = 2S unpolar = 2(2.0) = 4.0 W/m 2<br />
b) Maximum transmitted intensity S = S max = 8.0 W/m 2 occurs at θ max .<br />
S is maximum when S polar = S 0,polar (when θ = 20 o + 90 o = 110 o = θ max )<br />
S max = S 0,polar + S unpolor è S 0,polar = S max - S unpolar = 8.0 - 2.0 = 6.0 W/m 2
