In this video I teach you about how polarizers work. I then show you how an LCD screen works and how you can use this information to make super-spy glasses that lets you see an image on a screen that just looks white to everyone else!

I've always had trouble getting my head around the polarisation of light effect you show in the first half of this video - but then at 2:37 you made it finally click for me! The light *doesn't* 'go through' the filter (even though effectively it does, and we refer to it that way), it is _absorbed_ by the filter and then _emitted_ from the other side. Score a science win for the Action Lab! :-)

@derekmcdaniel6029 5 лет назад

From the beginning of the video, it's not clear to me, are all possible polarizations of light linear combinations of vertically and horizontally polarized light? I expect there is nothing special about the horizontal or vertical orientations, and those are just used as basis vectors, for example you could also have the polarity along diagonals. Am i understanding this correctly? Also, It's unclear to me how a rotating polarization would come about from combining vertical or horizontally polarized light.

@kenlogsdon7095 5 лет назад

Circular polarization is created by combining a source of EM radiation with a 90 degree phase shifted version of itself.

@TheActionLab 5 лет назад

Yes, basically linearly polarized light is in a superposition of right and left circularly polarized light and circularly polarized light is in a superposition of linearly polarized light.

I think IMAX, and maybe some other 3D movie theaters, might have the polarization in each lens of their 3D glasses oriented 90 degrees from each other, so they can project both polarizations on to the screen, but each side blocks about half. Also, I have heard about taking the polarizer off of a display and causing you to see only a white screen a couple of years ago. It's pretty cool to actually see it - and I'm not counting those commercials about that one brand of sunglasses!
