Question

What is polarisation.........?????????What are the types of polarisation.......?????

Answer 1

the action of restricting the vibrations of a transverse wave, especially light, wholly or partially to one direction

Electronic Polarization, Ionic Polarization, Orientation Polarization and Space Charge Polarization.

Answer 2

Polarization is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. ... In linear polarization, the fields oscillate in a single direction

There are four types of Polarizationlike Electronic Polarization, IonicPolarization, Orientation Polarizationand Space Charge Polarization. The displacement of charge and formation of dipole in dielectric material when placed in an external field is calledPolarization.
