Do you mean polarisation in chemistry or light?

Since the 80's, an explanation for group polarisation has been on offer
based on Social Identity Theory .(from Hogg and Turner - called the
Theory of Referent Informational Influence)) The idea here is that when
subjects find themselves part of a discussion group then they tend to
self-categorize themselves in terms of membership of that group and
thereby construct a social identity for themselves. Part of this process
involves attempting to adopt the ingroup's perceived norms. Now one
image the group member may have of these norms, the theory suggests,
is that they occupy a position on some psychological dimension which
minimises ingroup differences and maximises ingroup/outgroup
differences.

In electrodynamics, polarization (also spelled polarisation) is the property of electromagnetic waves, such as light, that describes the direction of their transverse electric field. More generally, the polarization of a transverse wave describes the direction of oscillation in the plane perpendicular to the direction of travel. Longitudinal waves such as sound waves do not exhibit polarization, because for these waves the direction of oscillation is along the direction of travel.

Polarization (Brit. polarisation) is a property of transverse waves which describes the orientation of the oscillations in the plane perpendicular to the wave's direction of travel. This concept is used in areas of science and technology dealing with wave propagation, such as optics, seismology, and telecommunications. In electrodynamics, polarization characterizes electromagnetic waves, such as light, by specifying the direction of the wave's electric field. Longitudinal waves such as sound waves in liquids and gases do not exhibit polarization, because for these waves the direction of oscillation is along (and thus is uniquely determined by) the direction of wave's travel. In contrast, the direction of the (electric field) oscillation in electromagnetic waves is not uniquely determined by the direction of propagation. Similarly, the direction of shear stress in a transverse sound wave in a solid can have any orientation in the plane that is perpendicular to the propagation direction. The term polarization thus describes the possible orientations of the oscillatory process in the plane perpendicular to the transverse wave's path. go to the site below.. and u'll understand more about polarisation..

polarisation simply means creating polarity gradient. it specifies a particular direction of the phenomena.

polarization is a phenomena. light vector vibrate or rotate in two particual direction. so when light passed through quartz cryastal the light vector vibrate in only one direction. this is called polarization. quartz crystal are known as polarized material.
the light is called polarized light. polarization depends on angle. at which angle light passed thru material.
there are different type of polarization plane polarization, cylindrial polarization and elliptical polarization
