Polarization?

Question

i ve tried sites to understand the 'polarization'. but i don't understand it so far. can someone help me out with that? thanks in advance

Answer 1

Well these guys have done polarization of waves fairly comprehensively.Polarisation of electrodes is another possibility.this happens when an electrodes surface becomes changed by an adsorbed element,typically adsorbed hydrogen.It happens in old type dry batteries.We should have dealt with it now I hope. A new thought,magnets are polarised.

Answer 2

Polarization is a property of waves that describes the orientation of their oscillations. For electromagnetic waves such as light, the polarization is described by specifying the direction of the wave's electric field.

Most light is non-polarised, with the exception of that produced by lasers, I think.  

A specific orientation of polarity of light can be selectively transmitted with certain techniques (absorption, scattering, reflection and birefringence).  Thus the light transmitted by these means will be "polarised", but will be of lesser intensity than the source of non-polarised light that it came from (since perhaps 99% of the original light will have been filtered out).  Certain materials can twist light, I think its because of their molecular dipole moments.  Its all rather complicated and it gives me a bit of a sore head, plus I did it years ago!

Answer 4

It would help if you said polarisation of what exactly ?

you probably mean light, you have pretty technical answer above so let me use an example.

Polaroid glasses are horizontally polarised  and thus block light bouncing off surfaces like water or roads - what you see as "glare".  They block horizontal rays but allow vertical ones through.

If you take two Polaroid lanes and rotate one 90 degrees with respect to the other they block then horizontal and vertical light waves and indeed you can not see through then any more.
