*Clarification:* In my quantum animations, that is not multiple photons taking different paths. It is a _single photon_ taking multiple paths simultaneously. We're releasing only one photon at a time. Adding those phasor arrows together gives us the _probability_ of receiving a single photon at any given moment. *Minor Correction:* I show the paths leaving the source at the same time and arriving at the detector at different times, when it should actually be the other way around. Paths that take more time should be leaving the source earlier in order to arrive at the detector at the same time as the others. The reason we can add the phasor arrows together is because the paths arrive at the detector at the same time.

It's a cool video, but I'm surprised with people saying it's a "great explanation" and "coherent" since these phase vectors (as in other video as well) does not seems to cancel out at all, I mean I don't understand, how do they cancel? The Sum vector for them (from the beginning of the first arrow to the end of the last one) is pretty big and I'd assume that IF they cancel THEN it would be close to zero length, this is a huge inconsistency for me... @The Science Asylum please explain this Nevertheless the part with removing parts of the mirror was super interesting, can this be visualized with a real-world experiment? Is a demonstration even possible?

@ScienceAsylum

@@MrSenger00 The only reason they're not perfectly canceling in the video is because there's only 13 arrows in the animation. In reality, there are an infinite number of arrows. There are many arrows for paths _between_ the ones I've shown and many more arrows for paths _off screen._ They would cancel better if I considered 100 paths or 1000 paths instead of 13.

Everyone: Mirrors are simple. Light goes in one way, it comes out another way. Internet plebs: Mirrors are simple. When light hits the reflective coating on the surface, it bounces at an angle according to the law of reflection. Nerds: Mirrors are complicated. A usually silver or similarly reflective element that is electroplated onto the surface to serve as the mirror, will absorb incoming light, and vibrate. Those atoms will begin to emit their own light, in all directions, most of which destructively interferes except for in the directions that happen to match up with the predictions of the law of reflection.

A path integral on the otherhand sums the Integrand, a so called functional, a function of all possible paths, given as all possible vectorlike functions, by all these different paths, i.e. functions.

@@ScienceAsylum Why say it like that? You definitely cover pretty complex topics, but you do so in a way that even kids could understand some of it. Of course, there's only so much someone can get without having the math background though. Math makes physics make so much more sense.

@@Lucky10279 I'm saying it like that because of the new implementation of the COPPA law in the United States. This week, all KZread channels are forced to declare if our content is for kids and I'm still a little bitter about it. (Also, if I made a show intended for children, I'd use a lot fewer jargon words.)

"Why do math with symbols when you can do it _visuallly_ instead?" I'm really torn about this statement. I know what you mean and I really like to get a visual understanding of unfamiliar concepts. But at the same time, I can't help but be greatful that we _can_ do math symbolically. It makes things so much more efficient. I'd drive me crazy if I had to actually draw vectors everytime I needed to add vector quantities or do the dot or cross product. I know you weren't saying that all math should be done visually, but I thought I'd share, since a lot of people don't realize how lucky we are to live in a time when so much useful mathematical notation has already been invented. When my algegra students get frustrated about having to learn the new notation, I tell them to imagine having to write out all the equations and compact expressions as entire paragraphs of text, and they pretty quickly get the picture (pun not intended).

Yeah, I mean, if you want _actual accurate_ numerical answers, you need to use the symbols. But, if all you need is a conceptual understanding, the symbols are overkill.

I'm an ordinary student. But I had this question in my mind that the reflection of light, EM waves was not the axact thing we are taught of,I tried to find an answer.And when watched this video It came in to my mind that I have go further to get a wholsome answer. Yet I'm very glad to know that my question is more worthy than I thought. Thanks for this video.

I read Feynman's QED twenty years ago, and I remembered many things you illustrated here, but either Feynman didn't discuss, or I just didn't remember, the concept that the photon actually travels all paths at once -- rather than using the probabilities to select a single path. Thanks for improving my understanding!

When he said "or does it?" the quantum probabilities of Vsauce being in the video intensified.

That's only true if you're just seeing eye to eye. In certain angles, as long as I avoid pointing to your eye, I can see your other body parts while you won't see any of my body parts.

@@yvrelna very true. also I wonder if our eyes were in a vertical line instead of horizontal, would the flipping effect follow suit?

Excellent video! Keep up the good work! 👍🏻

Mr. Asylum. The best video on mirrors I've ever seen. (Ok, yes it was my first and only)😬no really awesome video!!👍🏼👍🏼

I finally get the answer I want,bcs my high school teacher don't even know how to explain(or don't even know) why mirror reflect like that

you mean "like that" as in left-to-right (apparently), or "like that" as in at the same angle? :-B

This channel is absolutely amazing, I feel crazy enough to be admitted to the Science Asylum after watching 😂🤪

What an excellent explanation of the quantum physics of light and mirrors.

I had this question in my head for years and now, finally, you explain it better than anyone could do it Thanks
