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 ...
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 ...
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.
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 ...
Polarizing filter (photography) 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 ...
Polarizers are used in many optical techniques and instruments. Polarizers find applications in photography and LCD technology. In photography, a polarizing filter can be used to filter out reflections. The common types of polarizers are linear polarizers and circular polarizers.
Polarization (electrochemistry), a change in the equilibrium potential of an electrochemical reaction. Concentration polarization, the shift of the electrochemical potential difference across an electrochemical cell from its equilibrium value. Spin polarization, the degree by which the spin of elementary particles is aligned to a given direction.
Construction. 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.
