What is the Effect of Brewster's Angle on Refracted Light?

[kususe]

If a ray hits a medium with Brewster's angle, reflected light is linear polarized {if electric field way is not parallel to incidence way}. But what does it happen to refracted ray?

Thanks you in advance

If the incident light is polarized parallel with the surface, then all of it will be reflected with no refraction. If the polarization of the incident light is other than parallel, the portion that is NOT polarized parallel with the surface will be refracted.

If the incident light is randomly polarized, and incident at the Brewster angle, then the refracted light will be partially polarized.

Using Don's figure: 100% of the || light is transmitted, and about 85% of the _|_ light is transmitted. So the polarization is more || than _|_.
