polarization po·lar·i·za·tion (pō'lər-ĭ-zā'shən)
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.
In politics, the grouping of opinions around two extremes: “As the debate continued, the union members were polarized into warring factions.”
Note: 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.
