Input (English): The field of this name is defined as the average dipole moment per unit volume of a dielectric material. A phenomenon given this name can be described by a system in which the multiplication of Jones vectors by Jones matrices represents the manipulation of this property by a linear optical element. This property is completely characterized by the (*) Stokes vector and can be altered by phase retarders. In one form of this property, the electromagnetic field only oscillates in one plane. This property comes in circular, elliptical and linear forms. For 10 points name this property of light that is exploited to reduce glare by some sunglasses.
Output (English): Science
