'Evolution of polarization along a single mode fiber' -- subject- s -: Optical fibers

How can you determine the polarization axis for a single sheet of Polaroid?

electronic polarization

ionic or atomic polarization

orientation or dipole polarization

space charge polarization

No. It is the exclusion or joining the many perspectives into a single one.

Longitudinal waves doesn't exhibit polarization or diffraction; these to features are for transverse waves.
