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) and affective ...
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 ...
Group polarization. In social psychology, group polarization refers to the tendency for a group to make decisions that are more extreme than the initial inclination of its members. These more extreme decisions are towards greater risk if individuals' initial tendencies are to be risky and towards greater caution if individuals' initial ...
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 ...
The polarimeter is made up of two Nicol prisms (the polarizer and analyzer). The polarizer is fixed and the analyzer can be rotated. The prisms may be thought of as slits S1 and S2. The light waves may be considered to correspond to waves in the string. The polarizer S1 allows only those light waves which move in a single plane.
Racial polarization. Racial polarization is the process whereby a population of individuals with different ancestry is divided into separate and distinct racial groups.
Polarimetry of thin films and surfaces is commonly known as ellipsometry . Polarimetry is used in remote sensing applications, such as planetary science, astronomy, and weather radar . Polarimetry can also be included in computational analysis of waves. For example, radars often consider wave polarization in post-processing to improve the ...
Polarizability. 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. When subject to an electric field, the negatively charged electrons and positively charged atomic nuclei ...
