a sharp division, as of a population or group, into opposing factions.
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.
- the deposit of gases, produced during electrolysis, on the electrodes of a cell, increasing the resistance of the cell.
- a vector quantity indicating the electric dipole moment per unit of volume of a dielectric.
- the induction of polarity in a ferromagnetic substance.
the production or acquisition of polarity.

The restoration of a polarized state across a membrane.
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.
The coating of an electrode with a thick layer of hydrogen bubbles, with the result that the flow of current is weakened or arrested.
The development of differences in potential between two points in living tissues, as between the inside and outside of the cell wall.

A condition in which transverse waves vibrate consistently in a single plane, or along a circle or ellipse. Electromagnetic radiation such as light is composed of transverse waves and can be polarized. Certain kinds of light filters, including sunglasses that reduce glare, work by filtering out light that is polarized in one direction.
The displacement of positive and negative electric charge to opposite ends of a nuclear, atomic, molecular, or chemical system, especially by subjection to an electric field. Atoms and molecules have some inherent polarization.
An increased resistance to the flow of current in a voltaic cell, caused by chemical reactions at the electrodes. Polarization results in a reduction of the electric potential across the voltaic cell.

Reflected light, such as the light that produces glare on a sunny day, is polarized so that the electrical field is parallel to the ground. Some sunglasses are designed to take advantage of this property by blocking out that particular polarization while allowing other light to come through.
In politics, the grouping of opinions around two extremes: “As the debate continued, the union members were polarized into warring factions.”
