2. polarization a state, or the production of a state, in which rays of light or similar radiationexhibit different properties in different directions.
1. (noun)polarization, polarisation the phenomenon in which waves of light or other radiation are restricted in direction of vibration
2. (noun)polarization, polarisation the condition of having or giving polarity
Definition of 'polarization'
Webster Dictionary
1. (noun)polarization the act of polarizing; the state of being polarized, or of having polarity
2. (noun)polarization a peculiar affection or condition of the rays of light or heat, in consequence of which they exhibit different properties in different directions
3. (noun)polarization an effect produced upon the plates of a voltaic battery, or the electrodes in an electrolytic cell, by the deposition upon them of the gases liberated by the action of the current. It is chiefly due to the hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro-motive force, both of which tend materially to weaken the current of the battery, or that passing through the cell
Definition of 'polarization'
The Standard Electrical Dictionary
1. polarization (a) The depriving of a voltaic cell of its proper electro-motive force. Polarization may be due to various causes. The solution may become exhausted, as in a Smee battery, when the acid is saturated with zinc and thus a species of polarization follows. But the bestdefinition of polarization restricts it to the development of counter-electro-motive force in the battery by the accumulation of hydrogen on the negative (carbon or copper) plate. To overcome this difficulty many methods are employed. Oxidizing solutions or solids are used, such as solution of chromic acid or powdered manganese dioxide, as in the Bunsen and Leclanché batteries respectively; a roughened surface of platinumblack is used, as in the Smee battery; air is blown through the solution to carry off the hydrogen, or the plates themselves are moved about in the solution.
