The light is polarized in the ydirection. The axis of the first polarizer is at 01 22 o the y direction. The axis of the second polarizer is at th2 44 to the y direction The inlensity of the initial beam of polarized light is 10 Assignment Status Polarized Light Click here for Otheexpertta.com detailed view A 25% Part (a) Express ty of the ight after passes through he fi zer, I ns of and pola Problem Status Grade Summary Completed Potent 00% Completed Partial cos (o) cos(A821) cos(p) 7 8 9 Submissions Attempts remaining: cos (0) cos (el) sin(a) per attemp) detailed view VO Feedback deduction per feedback Hin 4 25% Part (b) Express the intensity of the light after itpasses through the second pola 1, in terms of I1, A012, where AD A 25% Part (e) If fis the fraction of the light transmitted through the two polarizers, express fin terms of61 and A012. where A012 -01 El 4 25% Part (d) Solve for the numerical value off. 3:32 PMExplanation / Answer
(A) I1 = Io ( cos(theta1))^2
(B) I2 = I1 (cos(theta2 - theta1))^2
I2 = I1 (cos(theta12))^2
(c) I2 = Io (cos(theta))^2 (cos(theta12))^2
fraction = I2 / Io
= (cos(theta))^2 (cos(theta12))^2
(d) fraction = (cos22)^2 (cos(44- 22))^2
= (cos22)^4
= 0.739
