I believe Daniel Lima is correct. A polarizer with a vertical grating ABSORBS vertically-polarized light, because it is the vertical direction in which electrons in the material are free to absorb the photons' energy and express it as increased kinetic energy (i. e. increased motion. Since horizontally-polarized photons cannot be absorbed, though, they simply pass through.

Hi,
Was there meant to be the next episode in this series released on Friday 10th February 2017? I thought one episode is uploaded every Friday? Is this wrong, or is the episode just a bit delayed going out? I'm using this video series as part of my AS level Physics revision.
Thank you,
Lewis.

My physics teacher said I won't need to take exams for the rest of the year if I find the model of a lens that:
1. Becomes thinner as you approach the edges
2. Has a higher refraction index than it's environment
3. Diverges light
So here I am doing my research -

What happens to the magnetic field because if an electric field is parallel to transmission axis, the magnetic field must be perpendicular to the axis. Does it is blocked there itself?
If yes, then why do we see light because light is composed of both the fields?

Great information but maybe don't edit out the pauses between each sentence next time as the content is delivered in what seems to be one giant sentence.

I can't look at some modern displays properly with my polarized shades. Sometimes, I get a large, black area. Other times, I see visible spectra.

So the flat water polarises the incident light ray horizontal? Or does the water just absorb more light which is not horizontally polarised?

That was Casey Neistat recording himself for his next video ft. Shini Somara. Next time, will it be Superwoman and her Rainbow?
