What is the angle from vertical of the axis of the second polarizing filter? Unpolarized light with intensity 350 W/m^2 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/m^2 . Express your answer to two significant figures and include the appropriate units.

Io =350 W/m^2
I = 126 W/m^2
From Malus law
I =(Io/2)cos2
126 =(350/2)cos2
cos2 =0.72
= 32
degrees
