Unpolarized light falls on an angle of 37.5 with a plan glass surface. The reflected light polarization is examined with a Polaroid. The ratio between maximum and minimum intensity from Polaroid when it is rotated around is 4.0. Which is the refractive of index glass?

I would like to use the equation which relates the Intensity with the incident angles with the refraction angle. But doesn't really find out how.

The relevant equations are Fresnel's equations:

Are you sure that this question is not more apt for the homework help forum?

Since the OP has posted the question in the homework forums, I am locking this thread.
