Unformatted text preview: Physics 241 Quiz 19a April 8, 2008 Unpolarized light of intensity I0 is sent through 3 polarizers, each of the last two rotated 45 from the previous polarizer so that the last polarizer is perpendicular to the first. What is the intensity transmitted by this system? I0 I1 I2 I3 a) 0.71 I0 b) 0.50 I0 c) 0.25 I0 d) 0.125 I0 e) 0 I1=(1/2)I0 I2=I1(cos 45)2 I3=I2(cos 45)2 ...
