    Understanding Polarization: Reflection and Refraction at a Water-Glass Interface

    A beam of unpolarized light (III=IP= I0 and EII= EP= E0) is incident from air on a plane interface of water (n = 1.33). (a) Under the incident angle of θi = 0°, 30°, and 70°, what is the amplitude (E) and intensity (I) of the reflected beam (relative to the values E0 and I0 of the incident...
