The emerging light strikes a second ideal filter whose axis is at 45.0 Enter the factor only. For example, enter 0.250, that means your answer is I 0.250 ar to that of the first Submit My Answers Give Up Part B Determine its state of polarization. The light is linearly polarized along the axis of the first filter O The light is linearly polarized along the axis of the second filter. The light is linearly polarized perpendicular to the axis of the second fter The light is linearly polarized perpendicular to the axis of the first filter. Submit My Answers Give Up

Explanation / Answer

let's say the first filter polarizes vertically
an ideal filter would only let 1/2 of the unpolarized light through
then
the second filter would only let ( I cos45 ) through
so
Io * 1/2 * cos45 = 0.3535 Io
and
it would still be vertically polarized (same as the first filter) because the second filter does not rotate the light, it just blocks some of it
