Confusion about polarization

    confusion about polarization....

    i have been confusing according this picture which is taken from http://hyperphysics.phy-astr.gsu.edu/Hbase/hframe.html.

    Confusion is "i studied that is when the reflect light perpendicular to transmitted light then two ways become plane polarize".but here reflection part get the plane polarization .but transmitted wave does not get any polarize.

    please help me . I'm very beginner for this subject...

    Are you talking about "Polarization by Reflection" http://hyperphysics.phy-astr.gsu.edu/Hbase/phyopt/polar.html#c1 ?

    The pictures shows light incident at the Brewster angle. This is the angle at which the p-component of light is 100% transmitted. Thus the only component that is reflected is the s-component, hence s-polarization of reflection.

    Note that the s-component is only partially reflected, so that the transmitted light still has the two polarization states. However, assuming no absorption, the transmitted light will have the same amount of p-polarization as the incident light but less in the case of s-polarization since part of it is reflected.
