Polarizing politics can also help to overcome internal differences and frame a common identity, based in part on a common opposition to those resisting reforms. Still, polarization can be a risky political tool even when intended as an instrument of democratization, as it risks turning pernicious and self-propagating.
Polarization (physics), the ability of waves to oscillate in more than one direction; polarization of light allows the glare-reducing effect of polarized sunglasses ...
Similar to other polarizing topics in the United States, a person's attitude towards COVID-19 became a matter of political identity. While the crisis had very little precedent in U.S. history, reactions from both liberals and conservatives stemmed from long-held messaging cues among their parties.
Linear polarizing filters were the first types to be used in photography and can still be used for non-reflex and older single-lens reflex cameras (SLRs). However, cameras with through-the-lens metering (TTL) and autofocusing systems – that is, all modern SLR and DSLR – rely on optical elements that pass linearly polarized light.
Devices that block nearly all of the radiation in one mode are known as polarizing filters or simply "polarizers". This corresponds to g 2 = 0 in the above representation of the Jones matrix. The output of an ideal polarizer is a specific polarization state (usually linear polarization) with an amplitude equal to the input wave's original ...
Social polarization is the segregation within a society that emerges when factors such as income inequality, real-estate fluctuations and economic displacement result in the differentiation of social groups from high-income to low-income.
Brewster's angle is often referred to as the "polarizing angle", because light that reflects from a surface at this angle is entirely polarized perpendicular to the plane of incidence ("s-polarized"). A glass plate or a stack of plates placed at Brewster's angle in a light beam can, thus, be used as a polarizer.
Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. It is a property of particles with an electric charge.
