Answer:
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.
