In this problem, we are polarizing light. We'll need Malus law which relates the intensity of the light to the angle between two polarizers.
Unpolarized light with intensity 350 W/m2 passes first through a polarizing filter with its axis vertical, then through a second polarizing filter. It emerges from the second filter with intensity 126 W/m2.
What is the angle from vertical of the axis of the second polarizing filter?
Express your answer to two significant figures and include the appropriate units.
