Two Polaroid filters are initially crossed. The analyzer is rotated through an angle of 55.0 degrees. Find the fraction of the intensity incident on the polarizer which passes the analyzer.
I used
I1=1/2 Io
I2= I1cos
I2= 1/2 Io cos^2(theta)
= 1/2 Io cos227.5°
= .393 Io
Is this correct or should the angle be 55 degrees??
