  2. Polarization (waves) - Wikipedia

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

    Polarization (also polarisation) is a property of transverse waves which specifies the geometrical orientation of the oscillations. [1][2][3][4][5] In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. [4] A simple example of a polarized transverse wave is vibrations traveling along a ...

  3. Polarizer - Wikipedia

    en.wikipedia.org/wiki/Polarizer

    A polarizer or polariser is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. [1][2][3][4] It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, known as polarized light.

  4. Political polarization - Wikipedia

    en.wikipedia.org/wiki/Political_polarization

    Political polarization. Political polarization (spelled polarisation in British English, African and Caribbean English, and New Zealand English) is the divergence of political attitudes away from the center, towards ideological extremes. [1][2][3] Scholars distinguish between ideological polarization (differences between the policy positions ...

  5. Circular polarization - Wikipedia

    en.wikipedia.org/wiki/Circular_polarization

    Circularly polarized light can be converted into linearly polarized light by passing it through a quarter-waveplate. Passing linearly polarized light through a quarter-waveplate with its axes at 45° to its polarization axis will convert it to circular polarization. In fact, this is the most common way of producing circular polarization in ...

  6. Political polarization in the United States - Wikipedia

    en.wikipedia.org/wiki/Political_polarization_in...

    Political polarization is a prominent component of politics in the United States. [1] Scholars distinguish between ideological polarization (differences between the policy positions) and affective polarization (a dislike and distrust of political out-groups), both of which are apparent in the United States. [2][3][4] In the last few decades ...

  7. Linear polarization - Wikipedia

    en.wikipedia.org/wiki/Linear_polarization

    Linear polarization. In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. The term linear polarization (French: polarisation rectiligne) was coined by Augustin-Jean Fresnel in 1822. [1]

    The study, which involved surveying more than 1,400 local elected policymakers and local civil service leaders, found that 87% of those surveyed said political polarization negatively affects the ...

  9. Polarizing filter (photography) - Wikipedia

    en.wikipedia.org/wiki/Polarizing_filter...

    A polarizing filter or polarising filter (see spelling differences) is a filter that is often placed in front of a camera lens in photography in order to darken skies, manage reflections, or suppress glare from the surface of lakes or the sea. Since reflections (and sky-light) tend to be at least partially linearly-polarized, a linear polarizer ...
