Polarization speaks to the orientation of a wave in space. Waves oscillate. They have a component or components that move or are in motion. And as regards the space through which they're moving, they may be moving "up and down" or "across and back" or at some angle relative to some "reference" like "up and down" as cited.

There are lots of different applications of the concept, and light, electronics and even something like seismology deal with the concept of the polarization of waves. Links can be found below to relevant posts.

When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.

What are the types of polarization in dielectric material?

There are three types of polarization in dielectric material, they are electronic polarization, ionic polarization and orientational polarization.

What is cross polarization?

Cross polarization is the polarization orthogonal to the desired polarization. For instance, if the fields from an antenna are meant to be horizontally polarized, the cross-polarization in this case is vertical polarization. If the polarization is Right Hand Circularly Polarized (RHCP), the cross-polarization is Left Hand Circularly Polarized (LHCP).

Does a mirror polarize the light?

Polarized light waves are light waves in which the vibrations occur in a single plane. The process of transforming unpolarized light into polarized light is known as polarization. There are a variety of methods of polarizing light. The four methods are : * Polarization by Transmission * Polarization by Reflection * Polarization by Refraction * Polarization by Scattering

What is the difference between electrical polarisation and dielectric polarisation?

in electric polarization ion is formed which have more tendency to form then magnetic polarization . in magnetic polarization just transfer of electron via flux . so the basic reason is that ion has more mobility constant then electric polarization is more faster then magnetic polarization.

What is cross-polarization?

AnswerIn RF communications, there are basically 3 common polarizations. They are horizontal polarization, vertical polarization, and circular polarization. Use the link below on antenna theory and see some examples and gather more information.Basically, polarization describes how the E-field is moving when it leaves the antenna.In horizontal polarization the signal moves in a horizontal fashion (-).In vertical polarization the signal moves in a vertical fashion (|).In circular polarization the signal moves in a circular fashion (O) with either left-handed or right-handed rotation.Now, when you want to talk to someone using horizontal or vertical polarization you want to match their angle of polarization exactly for the strongest signal.Cross-polarization is radiation orthogonal to the desired polarization. For instance, the cross-polarization of a vertically polarized antenna is the horizontally polarized fields.This is important to know because when you are setting up something like a satellite connection. In order to allow more signals through the satellite transponder within a fixed bandwidth and with decreased interference, the satellite makers alternate the polarization between adjacent transponder channels. (-|-|-|-|-|-|). Two adjacent channels can be "shoved right up against each other" and will interfere in a minimal way if they are polarized oppositely. Since interference affects their customers, satellite vendors are very touchy about proper polarization, and monitor gaps, called "guard bands" to ensure that you are properly aligned.
