Contemporary Examples of polarization
The astronomers found that of the 93 quasars in the sample, 19 exhibited a measurable amount of polarization.
The direction of polarization for a quasar is determined by the accretion disk surrounding it.
The authors took care to eliminate the possibility of other sources of polarization, which is always a concern in astronomy.

- the condition of having or giving polarity
- physics the process or phenomenon in which the waves of light or other electromagnetic radiation are restricted to certain directions of vibration, usually specified in terms of the electric field vector
Word Origin and History for polarization
- 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.
