Show work. Chapter 33, Problem 038 In Figure (a) below, unpolarized light is sent into a system of three polarizing sheets. The angles 0, 02, and 03 of the polarizing directions are measured counterdlockwise from the positive direction of the y axis (they are not drawn to scale). Angles 1 and e3 are fixed, but angle e2 can be varied. Figure b) gives the intensity of the light emerging from sheet 3 as a function of e2. he scale of the intensity axis is not indicated.) what percentage of the light's initial intensity is transmitted by the system when 02 31° 180 Number Units the tolerance is +/-3%

Explanation / Answer

from curve theta3 = 90 deg

after theta1, I1= I0/2

after theta2. I2 = I1 (cos31)^2 = 0.367 I0

after theta3 , I3 = I2 (cos(90-31))^2 = 0.097 I0

% of light = 9.7 %
