The light coming from the screen below is polarized, and the polarizer that he holds in front is polarized in the orthogonal direction. By inserting a third polarized filter at a 45 degree angle, you are actually allowing some of the initially polarized light to pass through the 45 degree angle sheet (since it isn't orthogonal), and then the process is repeated with the frontmost sheet. In essence, you are "twisting" the light by rotating in small increments instead.
Okay, I think I somewhat understand what's going on at 1:30. The incident light from the left filter is only allowing light to enter along its' polarizing axis, but you're able to get some component of the incident light back on the right filter, which is held orthogonal. But this doesn't seem inline with Malus's law.
I thought that the filter that I'm moving at 1:30 (which is between the LCD and the other filter), repolarizes some light so it can show through the other filter.
Very cool stuff. How does the incident light show through the orthagonally placed polarized filter, since the 2nd filter appears to bring back some light, after rotating the second filter some angle relative to the first filters' polarizing axis?
I would have thought that if at an orthagonal angle, there would be no way of getting more light back?
They should Make clothing out of that.......X-ray goggles lol

@winlamb1 The same polarization filters are on "3D Real" glasses you get at the movies. Pop the lenses out and rotate them as shown in the video.

its cool how polorized filters work

Sorry, I'm having trouble understanding this, as I'm studying this in class right now at Virginia Tech.

In other words, how can you explain what occurs at 1:30 during the video. Are the lenses polarized only in one direction?
PseudoScienceb20 3 years ago
Is your LCD screens polarized axis vertical? And the polarized axis of the lenses horizontal?
