Polarizedlight
Polarized light is light in which the electric field vector oscillates in a defined orientation, or in
Polarization can arise when light is emitted by anisotropic materials, reflected from a surface, or scattered
Types and representations: Linear polarization has electric field oscillating along a single direction. Circular polarization has
Measurement and notation: The polarization state can be described by Stokes parameters. The effect of a polarizer
Applications: Polarized filters are used in sunglasses and camera lenses to reduce glare; liquid-crystal displays control
Natural polarization: The sky often exhibits partial linear polarization perpendicular to the sun due to Rayleigh
