Eating animals creates a false sense for the need of competitive style of teaching (or anything else). Collaboration brings success, whereas, competition brings torment and even death. Go vegan❤
I might be 10 years late to watch this... But I really wantttt to thnks a lot to u guys itsss really clear my thought about polarized light... Thnkssssss
Thank you for this video. I'm doing an independent study of optics and couldn't really understand what polarization is from the text book. I don't have time for a 20 minute video. This video was short and to the point.
Great video, the illustrations really help, but, can you do a video showing what happens when you put a polariser inbetween the other two at 45 degree angle, because when you do half the light gets through the 3rd polariser that previously blocked all light, so the middle one must be changing the polariasion of the light.
Hi Darcy, You are correct that this mechanical model is not consistent with the way an Electromagnetic wave would get polarized. In the EM model the wave would penetrate with its polarization vector perpendicular to the axis of the planes.
you mad me to love physics i always fear about physics, even thinking about that gaves me headache, but now when i thought about physics i have this channel so no worries
This video was so short and suddenly made me understand all the things that my physics teacher couldn't. Could you do a video on how lasers and polarizers work? Thanks!
Interestingly enough you were able to demonstrate both transverse and longitudinal with the same media. So isn't it possible that light is the same type of media and capable of both transverse and longitudinal waves? What kind of waves does a slinky produce? Longitudinal or Transverse?
It is not possible that light is capable of both transverse and longitudinal waves. This is because a transverse wave can be polarized. the reasoning behind this is that there is a horizontal and vertical aspect to a transverse wave. If you cancel out the horizontal aspect the vertical aspect remains and vice versa. However, a longitudinal wave travels by compressing a expanding a medium. This is why sound waves (longitudinal waves) are able to travel through walls whereas visible light (transverse wave) is not capable of such a feat. This is why sound travels faster and farther in water than air because the medium is more tightly compacted, thus conserving energy. This also explains why there is no sound in space but light still exists. There is no medium for sound to travel through. Light waves, however, are capable of traveling in space because they don't require a medium. As for what kind of waves a slinky produces, it can produce either wave. It depends on how the slinky is acted upon, as demonstrated in the video.
