Extensive Definition Polarity in international relations is a description of the distribution of power within the international system. It describes the nature of the international system at any given period of time. There are three types of systems, Unipolarity, Bipolarity, and Multipolarity. The type of system is completely dependent on the distribution of power and influence of states in a region or internationally.

Chemical polarity In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules interact through dipole–dipole intermolecular forces and hydrogen bonds. Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure.

Polarization Polarization is a mechanism that typically results in a change in the potential of an electrode during electrolysis, when the anode’s potential becomes nobler than that of the cathode.

Polarization Cathodic protection refers to the application of a cathodic polarization to a corroding system. Concentration polarization of an electrode is the result of formation of a diffusion layer adjacent to the surface of the electrode where there is a gradient of ion concentration.

Electronic Warfare and Radar Systems Engineering Handbook - Polarization - The polarization of an electromagnetic wave is defined as the orientation of the electric field vector. Recall that the electric field vector is perpendicular to both the direction of travel and the magnetic field vector. The polarization is described by the geometric figure traced by the electric field vector upon a stationary plane perpendicular to the direction of propagation, as the wave travels through that plane.

Polarized pluralism Unsourced material may be challenged and removed. (September 2007). Polarized pluralism is a description applied to a two-party or multi-party political system which is seen as overly polarized and therefore as dysfunctional. It was originally described by political philosopher Giovanni Sartori to define a system where moderate views are replaced by polarized views.

Polarization Polarization. A light wave is an electromagnetic wave that travels through the vacuum of outer space. Light waves are produced by vibrating electric charges. The nature of such electromagnetic waves is beyond the scope of The Physics Classroom Tutorial.

polarized To separate or accumulate positive and negative electric charges in two distinct regions. Polarized objects have an electric dipole moment and will undergo torque when placed in an external electric field.

Polarization (waves) One may then describe the light in terms of the degree of polarization, and the parameters of the polarized component. That polarized component can be described in terms of a Jones vector or polarization ellipse, as is detailed above.

Polarity Home » Polarity. Definition. noun. (1) The presence of or having distinct and opposite poles. (2) The condition of having contrasting properties or direction. (3) (chemistry) The tendency of forming distinctive opposing charges based on the orientation of chemical bonds and spatial structure of the molecule.

âPolarizedâ or âpolarizingâ opinions? “Polarized” or “polarizing” opinions? English is a foreign language to me, and one word that is particularly confusing is polarize. In physics, it has contradictory definitions; when polarizing waves you remove inequality, but polarizing can also mean to cause something to acquire polarity, or in other word emphasize inequality. When applied to opinions, however, people usually seem to have the second definition in mind.

- If a collection of non-polar molecules. is subjected to an applied electric field the polarization is. induced only in their electron distribution. However, if. molecules in the collection possess a permanent ground. state dipole moment, these molecules will tend to reorient. in the applied field.

polarization of light Examples are the reflection and refraction of light, in which polarization is caused by the difference in the optical characteristics of the interface of two media for the components of a light beam that are polarized parallel and perpendicular to the plane of incidence.

Polarization curve of a PEM fuel cell with poor oxygen or proton transport in the cathode catalyst layer The polarization curve is a “portrait” of a fuel cell; measuring this curve is a simple and routine procedure. A number of attempts have been done to suggest simple semi-empirical analytical equations for the cell polarization curve (see e.g. [5] , [6] and [7]).

polarization Elimination or neutralization of polarity, as in nerve cells. n. The production or condition of polarity. A process or state in which rays of light exhibit different properties in different directions, especially the state in which all the vibration takes place in one plane. The partial or complete polar separation of positive and negative electric charge in a nuclear, atomic, molecular, or chemical system.

Polarization (waves) Light is also partially polarized when it reflects from a surface. According to quantum mechanics, electromagnetic waves consist of particles called photons. When viewed in this way, the polarization of an electromagnetic wave is determined by a quantum mechanical property of photons called their spin.

Polarization (waves) Light is said to be partially polarized when there is more power in one polarization mode than another. At any particular wavelength, partially polarized light can be statistically described as the superposition of a completely unpolarized component, and a completely polarized one.lectromagnetic waves such as light exhibit polarization, as do some other types of wave, such as gravitational waves. Sound waves in a gas or liquid do not exhibit polarization, since the oscillation is always in the direction the wave travels.

Rheumatoid arthritis: Can it affect the eyes? Rheumatoid arthritis is primarily a joint disease. However, rheumatoid arthritis occasionally affects other parts of the body — including the eyes.The most common eye-related symptom of rheumatoid arthritis is dryness. Dry eyes also can be a symptom of Sjogren's syndrome — an autoimmune disorder that's often associated with rheumatoid arthritis.f you have rheumatoid arthritis and experience eye pain, vision changes or other eye problems, consult an ophthalmologist for an evaluation. Early treatment can help prevent vision-threatening complications.

polarization a sharp division, as of a population or group, into opposing factions. 2. Optics. a state, or the production of a state, in which rays of light or similar radiation exhibit different properties in different directions. Compare circular polarization, elliptical polarization, plane polarization.

Polarization Perhaps the biggest misconception that pertains to polarization is the belief that polarization involves the charging of an object. Polarization is not charging! When an object becomes polarized, there is simply a redistribution of the centers of positive and negative charges within the object.

polarized The definition of polarized is something that causes light to vibrate in a pattern or that causes something to have opposite (positive and negative) charges. An example of something polarized are the lenses in sunglasses. An example of something polarized is an electrical circuit.
