PLEASE SUPPLY ANSWER AND SHOW WORK

Light is incident from the left on two pieces of polarizing material, 1 and 2. As part a of the drawing illustrates, the transmission axis of material 1 is along the vertical direction, while that of material 2 makes an angle of theta with respect to the vertical. In part b of the drawing the two polarizing materials are interchanged. Assume that the incident light is unpolarized and determine whether the intensity of the transmitted light in part a is greater than, equal to, or less than that in part b. Justify your answer. Repeat part , assuming that the incident light is linearly polarized along the vertical direction.

Explanation / Answer

a) always loose half of unpolarized on first

so first case I0/2 cos(theta)^2

same in second

so equal to

b)

now since initially polarized veritcal

cos(0)^2*cos(theta)^2 = cos(theta)^2

second case
cos(theta)^2*cos(theta)^2
so greater than
