Question

In the figure below, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of ?1 = 39

In the figure below, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of ?1 = 39°, ?2 = 21°, and ?3 = 43° with the direction of the y axis. What percentage of the light's initial intensity is transmitted by the system? will give additional points for right answer as well as an explanationas to how you got it that I can understand.

Explanation / Answer

You need to calculate the effect of each polarizing sheet separately.

The first sheet reduces the intensity by 50% as it filiters out one component of the unpolarized light.

Use your formula to find the intensity transmitted by the second sheet
