Problem three: unpolarized light with intensity of 1350 w/m2, which is the intensity at an earth-orbit space telescope monitoring the sun, passes through four polarizers. the first has an angle of 30 degrees, the second with 35 degrees, third with 70 degrees, and fourth with 90 degrees, all angles with respect to vertical. a. what is the resulting intensity? b. what are two (of several, so pick two) changes you can make to ensure no light will pass through?
