Reflected and refracted rays are completely polarised with their planes of polarization perpendicular to each other

Reflected light is plane polarised but transmitted light is partially polarised

Reflected light is partially polarised but refracted light is plane polarised

At Brewster’s angle, only the reflected light is plane polarised, but transmitted light is partially polarised.
