A polarized beam of intensity Io is directed into a device consisting of two polarizers. The beam is vertically polarized, and the transmission axis the first polarizer is 23 degrees with respect to the vertical direction. If the transmission axis of the second polarizer is horizontal, what is the intensity of the light transmitted through the second polarizer?

Explanation:

The intensity of polarised light after polarization through angle θ

I = I₀ cos²θ

Here θ = 23 for first polariser

Intensity after first polarisation

= I₀ cos²23 = .846 I₀

For second polariser θ = 90 - 23 = 67 degree

Intensity after second polarisation

= .846 I₀ cos²67 =  .13 I₀ .

the answer is to check all of them! they all apply well at least i think so!

yup its correct its: c) b b
