How do you know when the polarization in your shades is wearing out?

A test would be to find a car with stock AC after 1994, put on your polorized shades and look at the side or back windows. You should see different shades of squares. The windows are made with a coating to help keep in the AC better. Your glasses let you see this, but because the glass and you are at different angles, you see different shades with your shades.

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

How do you measure cross polarization?
cross polarization = xpd so, xpd = 20 log E11/E12 where E11 and E12 are the two waves.
How many shades of blue are there?
There are an infinite number of possible shades. Each shade of blue can be modified slightly by adding a new colour, the possibilities are endless. As far as we know, there are more than fifty thousand shades of blue. Air Force Blue, Celeste, Egyptian blue, Maya Blue, Royal Blue, and Ultramarine are a few.
When was Small Angle Shades created?
Small Angle Shades was created in 1758.
Does wearing two shades of gray make them match?
yes

Shades
What sunglasses are the last pair Usher is wearing in the Lemme See music video?
I really wanna get this type of shades to put on its really beautiful.anyone with the answer please lemme know.
What are the types of polarization?
electronic polarization ionic or atomic polarization orientation or dipole polarization space charge polarization
What shades are good for brown eyes?
I would think that eye color would be irrelevant when choosing sunglasses (shades), since the eyes cannot be seen while wearing them.
A guy wearing shades a long black coat black gloves and sword on his back. who is he?
Blade
Longitudinal wave do not exhibit in polarization or diffraction?
Longitudinal waves doesn't exhibit polarization or diffraction; these to features are for transverse waves.
What is activation polarization?
activation polarization is a polarization due to charge transfer kinetics of the electrochemical process involved.
Polarization is a property of?
Polarization is a property of transverse waves.
Are there eighty shades of white?
There ARE 80 major shades of white but many other shades too. Lol I don't know why so many =P
Should you wear pink and yellow colours together?
pastel shades of pink and yellow can go together nicely,however if you were thinking of wearing brighter shades together it may look too much :)
