Light Polarization

Just using some polarization filters for some cool effects on my liquid crystal display.

Physics works!

The piece of polarizing film is set 90 degrees to the polarizer on the LCD, blocking out most light. The filter added diagonally between not only blocks, but rotates some of this light from one orientation to the other, allowing it to pass.

quick question. when the one heet appears to be blocking all visible light when the other sheet is placed behind it you can then see thru it. how can this be explained?

@gtq838 It's because this first filter flipped the light waves by 90 degree (which made invisible for the human eye), and by applying the other filter, the light waves flipped again by 90 degree, which made it visible again.

@GeminiPaladin you mean noone with your brain capacity?

:O this is so cool. didnt know that you could do that



[sauroman1]

Where you found these filters? Do they cost a lot? Thanks

[TheMrNashville]

you can do this with the lenses from 3d glasses from a movie theater

[turbomother09]

the noise! why???????

[xollst]

dont show this to creationists, they will burn you as a witch :p

Just as noone really understands polarization, noone really understands electricity or anything positive or negative for that matter. There is only the vague notion of the idea.

is hthat the same stuff they use for lcds cos I was going to make a my coleco talking teachers lcd screen the oposite colour .Where did you get the polarizing film from?
