A 170 mW horizontally polarized laser beam passes through a polarizing filter whose axis is 26^o from vertical. Draw a picture that shows the angles, and remember that the angle in Malus' law is between the two polarization axes. Also, while Malus' law is written in terms of intensity, you can use this same equation for power instead of intensity.

What is the power of the laser beam as it emerges from the filter?
