this is what teachers in every corner of the world shud use to teach. this is 100 times efficient than what they explain in air. this shud be mandatory in all school. great work sir.

How does Eugene only have 220k subscribers? Everything about this channel is 10/10

The concept of sine wave was beautiful

You know what KZfaq lacks? A button to like every single video from a certain channel. Yours in particular. VERY helpful content. Although I'm not even studying this I still understand it with ease!

It's impossible to ever get disappointed by this channel... ; )

You should win a Nobel prize for making these videos... absolutely incredible

My heart aches for the students that still haven't find this chanel

I recently created a Patreon account for people who want to help support my channel. The link is on my KZfaq home page. Also, in case, you have not already seen them, I uploaded several other videos recently. As always, for each video that you like, you can help more people find it in their KZfaq search engine by clicking the like button, and writing a comment. Lots more videos are coming very soon. Thanks.

3D animation really helps make everything crystal clear! Would recommend this video!

Wow. I could have never been able to imagine this. Thanks a lot. Your animation are just fantastic, phenomenal.

The way you animated sin wave was amazing❤

The explaining style of this channel is great! The slow speed gives the learner enough time to think, to imagine. It's important for better understandings. Thanks for making such videos!!

Thank you so much for putting in so much detail in such a complex topic. I really appreciate the time you guys put in to y'alls video. I learned Fourier transform, electric current, and now diffraction interference from the videos you guys provide. Makes complicated topics into easy visualized understanding. Thank you. Keep up the good work!

Where have you been all my life, Eugene? This video is amazing - thanks for the thorough work you put into explaining these concepts!

Speechless and appreciation cannot be expressed in words. Making animation with concept is a big deal. Thank you for your hard work.

Wow. This was EXACTLY the level of clarity I was looking for and would be satisfied with when searching the web about how diffraction works. Delicious video. Exceeded my expectations.

This has to be the best video on a physical concept i have watched in my life. Thank you so much!

I usually do not like music in the background of educational videos. But there is something about classical music that fits math and physics beautifully. It compliments it instead of distracting.

This is the best and most illustrative tutorial on diffraction I have ever seen. Such animations are the perfect tool for really understanding such phenomena. Well done 👍

This is one of the best videos I've seen on interference and diffraction. Thanks a lot.

Why does this only have 7000 views?? It should be viewed by all physics/engineering students all over the world, it was amazing! I'm gonna tell all my class mates about this channel, and once I have a job, I'll be sure to donate too. :)Thank you so much!

This is so good I want to study here now ! This should be the way calm voice , calming music , perfect explanation from tip to toe!

Your videos are fantastic. The animation really helps for visual learners like me and to consolidate textbook type learning. Thank you.

You nailed it. After a long search, i found how interference happening through a single slit.

Videos like this are so important in advancing the understanding and teaching of physics. Your videos are always fantastic.

The sine wave analogy was really intruiging! Kudos to this amazing video!!!🎉

wow! this video is so helpful to my understanding of diffraction and interference. i have an excellent optics professor but lecture-style learning is inherently limited. sometimes you just have to sit back, get stoned and watch these mathematical concepts visually and graphically.

By far the best illustrated and explained series of lectures I've seen on the subject. There are some very odd experiments I have seen not very well illustrated but quite well explained; in which clever attempts where made to trick electrons into taking the wrong path. All attempts failed. The only explanation was that somehow the electron 'knows' ahead of time whither or not a barrier will be there thus always following the shortest path in the now. This left me scratching my head for years! It would be a challenge but I'm wondering if Eugene could produce a video addressing this phenomenality?

The best geometric description of wave interference I have ever watched

very good explanation you should really watch this video if you are stuck in the understanding of the ydse or diffraction through single silt.Kudos to the person who made this video possible.

This is the best explanation on aperture and depth of field on photography.

Very helpful video really good animation I totally visualized the concept thanks

I have no words in which I can thank you but i one thing, this is the only video i think which can explain it all , i mean its best... thanks a lot for making such a video ...

this is a wonderful way to convince the students about the behaviour of waves😇😇thank you

How beautifully one can explain....! You're the best.....❤️❤️❤️🙏🙏

This must have taken a lot of effort. You are sooooo amazing. Seriously.

Great great great video that actually uses Huygen's principle to explain diffraction Thank you for this

Fantastic video with music. Really helpful. Please do more videos.

Sometime my love for physics goes down but whenever I watch a single video on any physics topic from ur channel then it gets restored.

Best explanation I've ever seen.It is really amazing.Thank you very...... much.

You have some of the best videos on KZfaq, I wish I could help.

this video has broguht me great joy. it has cured my depression. 🥳 i am 7 years old

The 'single hole' interference pattern blew my mind the first time.

My god! This is the best explanation I have ever seen.

Thank you- this animation really helps me visualise things. It must've been hard work- really appreciate it and keep it up!

I loved every single bit of this video . Except the music ... It slowly makes one grow insane when learning a pretty complex topic. It's cloud nine of knowledge.

Finally, I was struggling to understand Wave Optics a lot until this video. Amazing, really amazing animation. If it was possible, I would've liked you to also dive into the mathematical aspects of it such as why the first dark fringe would appear when the path difference is equal to the wavelength and how it differs from YDSE and such. Still, I was finally able to understand the phenomena and I can take it from here. Thank you so much.

Such an awesome explanation.....I am really pleased as well as glad after understanding all the concepts of diffraction and interference so clearly....thanks a lot ma'am..

Sometimes understanding physics and imaging became hard but through ur well represented visual and slow lecturing video i will get time to think, imagine ,and makes relation b/n different concepts.Thanks a lots sir.

thanks sir for your one of the greatest videos again you have really great mind to made it i will see on the topics of planck foton theory and meaning of h what is h and how is work in equations

Loved the video loved the concept clarity given ❤️❤️❤️❤️

Thanks a lot, very helpful to visualize the effects!

Eugene this is a great video in many ways as usual, but it would been a really nice if you had elaborate more about the huygens principle.

Eugene: I really liked the phasor technique when the slit (d) becomes appreciably larger than lambda. I hadn't seen that before. A few questions about that: 1) This reduces to the standard Young Experiment when d>Lambda, does it make any sense to use a sub-source separation smaller than lambda? 4) What does a negative phasor magnitude imply (Partial trough?) 5) Are these techniques more applicable for fluid-waves rather than light-waves of single color? On a more important note, I presume these techniques are only an approximation to QED? As you know, QED produces ("amplitudes"--->probabilities at the back plane). I grapple with how simple phasor techniques which don't include quantum effects could match the mathematical Sum-over-history/Renormalization of QED. Thanks again for your beautiful vids.

This is the best thing that I ever saw for this topic

That cat which is in this video animation was confused like me before watching this video 😂😂😂😂but now that cat is become master in this concept 😂😂😂😂🤣🤣🤣🤣🤣and me also 😂😂thank u Eugene 💕🥰❤️👍u did a great job..

thank you!! love the background music choice btw 👩‍🚀

Incredibly great. Many thanks for sharing this!

This is a very important video in visualizing superpositions, although a video directed specifically at waves and superposition would be cool.

Great effort and nice way of explaining things :)

Great ❤✌️ superb explaination that can not be bought from everywhere

Superb, btw this might be one of the challenging videos for you, a lot of imagination and visualization is required

Eugene, YOU ARE THE BEST!

This channel should have 50 million subscribers... ♥

Awesome visualisation Thank you so much

Thanks so much, I understood lots of topics which ars really hard to understand. Please, keep going on this fantastic channel . My best wishes.

The music and everything is beautiful

Many Many thanks for this beautiful explanation

Great video, Thank you Eugene!

Amazing video!Helped a lot to visualise.Thank you so mich!

Best learning video I ever seen.

Great video as always!! It really helped me a lot, thank you!

this is the best video i can find. thks!!!

Thanku very very much all doubts are clear thanku

great videos. i realy like all your videos.

Very nice representation, thank you!

Ossom superb y'a ira really great video

Superb vlog of concept of sine wave

Is the behavior of the wave as a sum of smaller waves coming from the individual photons that form light?

This is amazing. This is a great channel.

Thanks a lot, your videos just come in time to save me from another test.May I know what your nest videos are going to be?I really your way of teaching thanks again

So each hole makes a new light source and the two source combine together and waves interfere makes patterns

Sir, you've nailed it.

loved the music AWESOME !!!!!

very beautifully explained!

Nice, excellent, marvelous, beautiful love u team.....

Excelent Video, only one Question, What is the size of the slit that makes the difraction bigger?

Magnificent Absolute beauty here mad lads 👏👏

i liked your videos it is so conceptual

I have never seen this explanation of interference and diffraction in my life before this.

I love people who make me love PHYSICS

These videos are incredible

Very insightful!

great job hats off👏👏👏🙌

Great like always!

Amazing vedio sir....thank u soooo muchhh

This is too good!Thank you for this!!

Amazing video! I really love how you're building off and combining old topics you already covered. One thing though, at around 12:38, doesn't that green line passing into the negatives on the x-axis suggest a negative amplitude, or is the only significant thing the actual length of the line? And if so, is there anything significant about the last point passing into the negatives? Thanks
