Please help me answer the following questions:

ADDITIONAL PROBLEM 1 Unpolarized light passes through two polarizers whose transmission axes are at an angle 0 with respect to each other. What should be the angle 0 between the transmission axes of the polarizers if it is desired that one-tenth of the incident intensity be transmitted? ADDITIONAL PROBLEM 2 Three polarizers are arranged as shown in the figure below. (Ignore the numerical values of 02 and 03 shown in the figure.) If the incident beam of light is unpolarized and has an intensity of 1.60 W/m2, find the transmitted intensity (a) when 02 = 25.00 and 03 = 50.00, and (b) when 02 = 50.00 and 03 = 25.00. 10 & = 30' A 8, =90 B 2 C
