This Demonstration allows you to visualize elliptical, linear, or circular state of light polarization. For a transverse electromagnetic wave propagating in the z direction, any polarization state can be expressed in terms of linear polarizations along the x and y directions, which are transverse to the direction of propagation. To visualize a state of polarization, vary the x or y components of the electric field (i.e., polarization), and/or the phase difference between the two-that is, the phase of the x component relative to the y component. The direction of electric field rotation (for elliptical and circular polarization) is coded using the visible part of the electromagnetic spectrum: red → yellow → green → blue → violetKnowledge in basic opticsComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
