Next video, early view
🕑 Added 2023-11-22 00:48:56 +0000 UTCHey folks, here's an early look at the upcoming video on the index of refraction.
A few sections, especially towards the end, don't have graphics yet. I know several things I'd like to change about the progression and framing, and since I'm planning to just do another recording of the narration, certain sections don't make sense to put graphics to until I know if/how they'll exist in the final version.
In the meantime, please do let me know what fixes you spot, and ideas you think need clarifying. I'll do my best to incorporate them, subject to the constraint of not wanting to bloat things too far beyond the 30 minutes it already fills up.

I think this helped answer an entirely unrelated question for me: Whenever I've been in a cave and they turned off the light to show how dark it was, I was always confused about what they meant by it being darker than anywhere else. Like: how was that darker than a room with no windows and a sealed door? Light didn't go through house walls just as it didn't go through cave walls, right? But this video makes me reconsider, specifically the part of about a material absorbing an electric field. Thinking about light not as a ray that is interrupted by a solid wall, but rather as a changing electric field that affects that wall clarifies that *some* continuing electric force is expected through the impediment. And it stands to reason that the amount a house wall absorbs the energy is different than the amount that feet of rock absorb the energy.

Very nice description. I'm looking forward to watching again once all the animations are done.

At 26:26, you talk about how an electron might "get pushed along a path with a counterclockwise component more freely than it gets pushed along a path with a left-handed component." I think the counterclockwise component should be a right-handed component, or the left-handed component should be clockwise, not mixed as it is.
