thank you so much! I'm normally okay with the concepts but just need more time for things to sink in, so a video format where it's all so clear and concise and I can pause or rewind as much as needed is amazing. I'm also quite visual so the words/colours/diagrams are great - thank you!!!

14:00 So the horizontal light being polarized is the B(magnetic field)?

11:55 I thought that the filters Blocked waves with the same orientation, as the waves are then able to transfer their energy into the filter as they oscillate in the same orientation. Rather than filters of the opposite orientation preventing the wave from going through. At least this is what my teacher taught us. I hope I've explained this well.

Phase and path diff?

If you add a third polarised filter at 45 degrees to two filters (one at 0 deg, the other at 90 deg) wouldn't the light then be able to pass through again? I read something about how light "forgets" the previous polarisation and acts as if it hasn't been polarised in the first direction.

0:45 If the water is only moving up and down why is it seen that it comes onto the shore? And we also move when the wave hits us. The water particles, the matter, is moving. It would be nice if you could clarify this

@amanamin3685

So the energy is carried by waves right as their primary function correct. So eventually they will start from one point and take energy to another So u can think of it as at the end of the medium that is the water. Some of the energy of the wave is converted to kinetic energy of water particles, and also sound is produced if u are on a beach isn't it.

Great video, but if the grating has bars in line with direction of his then they would be blocked, they would pass through a perpendicular grating, it is the other way around in this video, scientifically am I wrong? Polarised waves are formed when bars in line with oscillations absorb that axis of oscillation, I believe you have drawn with transmission axis but said that they are the actual bars.

You said 3x10^8 metres and then 300,000 m/s, just a small hiccup I think, thanks for the video anyways!

11:44 I don't this this is correct for all types of waves. We did an experiment with polarised Microwaves, and if they were oscillating vertically and the bars were also vertical, then the Microwaves were stopped. If the bars were changed to horizontal then the Microwaves passed through. It was explained as follows: The bars were made of metal, and so when the Microwaves hit the vertical bars they start oscillating the particles in the bars themselves and the Microwaves are absorbed and then re-emitted by the particles in all directions. If the bars are horizontal, then the Microwaves pass straight through the bars and into the detector. We tried this same experiment with a wooden set of bars and the explanation was upheld. But of course I have seen and played around with the polarised film where it blocks all light if you rotate them at 90 degrees. Now I'm not sure what to think.
