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?

Oh sorry, of course. Wont happen again. Thank you.

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