Please provide some theory for polarisation also!!

A circularly polarized monochromatic plane wave is incident on a dielectric interface at Brewaster angle. Which one of the following statements is correct? (a) The reflected light is plane polarized in the plane of incidence and the transmitted light is circularly polarized. (b) The reflected light transmitted light is plane polarized in the plane of incidence. c) The reflected light is plane polarized perpendicular to the plane of incidence and the transmitted light is elliptically polarized. (d) There will be no reflected light and the transmitted light is circularly polarized. plane polarized perpendicular to the plane of incidence and the

    the reason is, reflected light will be plane polarized in perpendicular to plane of incidence (this is the definition of Brewsters angle). and the transmitted light will become distorted from circular to become elliptical polarized light.

    in incident ray vibrations are in all possible directions while in reflected it's in place and in case of refrected it's out of plane so they would be plane polarised so option c is correct.

    Option C is correct. because the reason is, reflected light will be plane polarized in perpendicular to plane of incidence (this is the definition of Brewsters angle). and the transmitted light will become distorted from circular to become elliptical polarized light. for better understanding, see attached

    you can see, the transmitted light is partially polarized, hence it couldn't be plane polarized

    doubts will be entertained for sure.
