Interesting Circuits (Polarized Material) 002

I know its not a circuit but I am quite amazed at how this material reacts I think we may be able to use this to See Magnetic Flux Lines if more Filters are used.


Enjoy..

Double U, to the T to the fuck is up with dis shit?

[kubikop]

Weird isnt it!

[rroge5]

this has many applications.

[kubikop]

Yeah, its kewl isnt it.... ;-)

I guess the one under is actually twisting the light so that it can pass through the top one, maybe... I'm no expert :)

[kubikop]

May be your right, but light is meant to travel in a straight line??

I'm no expert either I just find it hard to believe that light travels in straight lines apart from when you have bits of plastic with small lines drawn on them? which is effectively what polarized material is...

Weird Huh! I Just want to make people think....

Thanks for watching.

They use this effect for filtering lights for movies. Light travels as electromagnetic radiation. So it's basically two waves of energy traveling at right angles to each other. Each piece of polarized material blocks either the light portion of the wave(photon), or the other half of the wave; depending on the angle at which you hold the material. So two pieces at 90 degrees to each other effectively block out all light.

On the right track i think

Take just the top one and the one behind, you will get half brightness as they are at 45 degrees, then you take the one behind and the screen, those are at 45 degrees too and will pass half the light.

however, if you put the second one in front, at some stage the difference is 90 degrees so light won't pass

True that light travels in straight lines, but as a wave, think of a rope being shaken through a 'grid', if the grid is inline, the rope moves like a wave

Paul, there's even more stuff that can be demonstrated than what you have shown here.

Try inserting other objects between the two polarising filters, instead of the third filter. I recommend a sheet of cellophane to start with.

There's a whole world of fun stuff with this.

You hit on it with the windscreens comment; the effect is only visible when there is natural polarised light (from the blue sky usually) passing through the windscreen and then through your polarised glasses.

[Other comment deleted for typos.]

So, if the photon polarization is shifted from sheet A 45° and again shifted by sheet B 45°, then sheet C will also accept that energy and re-emit it 45° shifted. Of course the camera sensor is not polarized, so it will accept the photonic energy whether it is 0° or 135°. And this case, the 3 layers shift the energy 135°. Two sheets rotated less than 45° will probably pass quite a bit of light. Adding more...well you get the picture ;-)
