Start with light that is initially polarized parallel to the x axis sent into a system of three polarizing sheets.

a. If we rotate the polarizing direction of the first sheet to 60o counterclockwise, what is the ratio of its final intensity I3 to its initial intensity I0 as I3/I0 from what is shown?

b. If we rotate the polarizing direction of the first sheet to 90o counterclockwise, what is the ratio of its final intensity I3 to its initial intensity I0 as I3/I0 from what is shown?

Answer are given as (I3/I0 (a); I3/I0(b))

answer choices:

0; cos^2(60)cos^2(?-60)cos^2(?-90)

0; 0.5cos^2(60)cos^2(?-60)

None of the above
