You could use Malus's Law. Malus's Law tells us that if you have a polarized wave (of intensity I 0 0) passing through a polarizer the emerging intensity (Y OR) will be proportional to the square cosine of the angle between the polarization direction of the incoming wave and the axis of the polarizer.

Explanation:

OR: I = I 00 ⋅ cos two (e)
