Игра Без Сохранений 2 (Мото VLOG) 58 min How the index of refraction arises, and why it depends on color (as seen with a prism) Quotebook Notebooks: https://3b1b.co/store These lessons are primarily funded directly by viewers: https://3b1b.co/support An equally valuable form of support is to simply share the videos. This video is largely based on the following Feynmann lecture https://www.feynmanlectures.caltech.edu/I_31.html Looking Glass Universe videos on the index of refraction: https://youtu.be/uo3ds0FVpXs The explanation for why the phase of a wave produced by a plane of oscillating charges is a quarter phase behind the wave of a charge in the center of that plane, and hence a quarter phase behind that of a light wave inducing the oscillations, is given in the previous chapter: https://www.feynmanlectures.caltech.edu/I_30.html Sections: 0:00 - The standard explanation 3:14 - The plan 5:09 - Phase kicks 8:25 - What causes light? 13:20 - Adding waves 16:40 - Modeling the charge oscillation 20:59 - The driven harmonic oscillator 26:57 - End notes Thanks to these viewers for their contributions to translations German: Ole Hebrew: Alon Altman, Omer Tuchfeld Hindi: Saurabh Portuguese: @doryhelioaires Urdu: Momini0 ------------------ These animations are largely made using a custom Python library, manim. See the FAQ comments here: https://3b1b.co/faq#manim https://github.com/3b1b/manim https://github.com/ManimCommunity/manim/ All code for specific videos is visible here: https://github.com/3b1b/videos/ The music is by Vincent Rubinetti. https://www.vincentrubinetti.com https://vincerubinetti.bandcamp.com/album/the-music-of-3blue1brown https://open.spotify.com/album/1dVyjwS8FBqXhRunaG5W5u ------------------ 3blue1brown is a channel about animating math, in all senses of the word animate. If you're reading the bottom of a video description, I'm guessing you're more interested than the average viewer in lessons here.
