  2. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Sound waves in solid materials exhibit polarization. Differential propagation of the three polarizations through the earth is a crucial in the field of seismology. Horizontally and vertically polarized seismic waves (shear waves) are termed SH and SV, while waves with longitudinal polarization (compressional waves) are termed P-waves.

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.

  4. Polarization - Wikipedia

    en.wikipedia.org/wiki/Polarization

    Polarization (physics), the ability of waves to oscillate in more than one direction; polarization of light allows the glare-reducing effect of polarized sunglasses Polarization (antenna), the state of polarization (in the above sense) of electromagnetic waves transmitted by or received by a radio antenna

  5. Elliptical polarization - Wikipedia

    en.wikipedia.org/wiki/Elliptical_polarization

    An elliptically polarized wave may be resolved into two linearly polarized waves in phase quadrature, with their polarization planes at right angles to each other. Since the electric field can rotate clockwise or counterclockwise as it propagates, elliptically polarized waves exhibit chirality .

  6. Electro–optic effect - Wikipedia

    en.wikipedia.org/wiki/Electro–optic_effect

    An electro–optic effect is a change in the optical properties of a material in response to an electric field that varies slowly compared with the frequency of light. The term encompasses a number of distinct phenomena, which can be subdivided into

  7. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    Circular polarization is often encountered in the field of optics and, in this section, the electromagnetic wave will be simply referred to as light. The nature of circular polarization and its relationship to other polarizations is often understood by thinking of the electric field as being divided into two components that are perpendicular to ...

  8. Polariton - Wikipedia

    en.wikipedia.org/wiki/Polariton

    A polariton is the result of the combination of a photon with a polar excitation in a material. The following are types of polaritons: Phonon polaritons result from coupling of an infrared photon with an optical phonon

  9. Physical optics - Wikipedia

    en.wikipedia.org/wiki/Physical_optics

    Physical optics is used to explain effects such as diffraction. In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid.
