Thin film interference and the beauty of soap bubbles

[@blenderguru]

This video is a gem. Thanks for helping so many people understand this phenomena. I'm using it to build a more realistic iridescent shader in Blender :)

Net path difference is 2utcosR+lembda/2 why???????????????????

[@arpitkeer7992]

Why lembda/2

[@deandrereichelle831]

Funny, I just saw this and was about to try simulating this with Mantaflow

[@shivankarsrijansingh2155]

@@arpitkeer7992 when a wave is reflected back it is has a pi phase difference

Best explaining of thin film interference I've seen so far with awesome visuals. I have subscribed:)

[@hileamlakmulugeta5959]

Me too. That is true Passion. Keep up the good work!

[@godhelpme8977]

Not really

[@vinayjumani839]

This is how physics should be taught, such a wonderful video on thin film interference!!!!!!! Thank you!!!!

[@TheSilentMajorityNation]

Thank you for teaching us film interference. I could watch videos like these all day!

[@aloevera420]

Thank you! I can understand thin film interference a little more now!! Plus, the personal engagement regarding photography on bubbles made this video more interesting

[@muhammadahmadkhalid364]

This is the second video I am truly liking in my life. Best graphical explanation with real own made videos. Stupendous!!!!!!!!

[@Nadyaboggo]

My child me playing in the bathroom making soap bubbles and being immersed in all the colors is so happy to see that someone has taken this seriously and there is so much to learn about soap bubbles! Thank you so much 💖💖💖

[@mukeshbhargava3011]

The best I have ever seen. Beautiful work...

[@ShailajaChadha]

so pleased to have come across this channel. subscribed!

[@henriquecsouza]

I was reading a Brief History of time from Stephen Hawking and in the 4th chapter he describes thin film interference, but I hadn't quite grasped the concept from the book's explanation alone. I came to youtube in search of a more detailed explanation that I could cope with because of my low level of physics knowledge. After watching your video it all just "clicked" and it makes perfect sense now. Thank you for the amazing explanation and phenomenal visuals. =)

[@prathamchauhan741]

Wow, same here bro

[@pierrepo1945]

I'm studying phyiscs ii - optics and this video help me a lot to understand Thin film interference. It is very practical and useful. Thank you.

[@utsah470]

the explanation could not have been better .... this video is insanely underrated.

[@utsah470]

Actually, I was looking for real thin films, after I studied this the class. that vertical soap film was the one I was looking for, and I mean it you did the job really perfectly. Your photography and videography skills are commendable, you brought the most out of it.

[@RamkrishanYT]

I don't know why I subscribed to this channel, but I'm really glad that I did

[@cvenkatesulu798]

This is the best video about thin film interference

[@karenl1921]

So beautiful the entire universe in the wings of a fly or a soap bubble. beautiful beautiful thanks for sharing !

[@indujahalder4152]

Best practical visualization on thin film interference.......thanks a lot... 👍👍.....

[@abdullahsajid4742]

You did a great work there.Such a detailed explanation of thin films.More power to you !!!

[@easthercules]

The bestest explanation ever

[@ezycuberz4563]

Picture wise and theory wise, I found this to be the bestestest video available in YT.. seriously, loved it! You are too much underrated... wish I could give you 1M subs right away, lol 👍✌

[@ericstahldavid]

Excellent video! Great explication and incredible photos!

[@chrispeoples4606]

Your presentation is truly awesome! I am definitely showing this in my AP Physics classes!

[@Kafiristanica]

I wanted to look up TFI and usually i'd first go to wikipedia, but today for some reason I decided to check youtube first, thinking in the back of my mind 'i'm only gonna find rough, shitty explanations with a lot of useless fluff'. You proved me wrong, good video.

[@Simonjose7258]

Beautiful pictures ✌

[@bloohblah268]

this video is genuinely amazing!

[@olafueberschar339]

Excellent video I also recommend my students to watch for illustration of optics lecture contents. Thanks a lot!

[@41-siddharthabehera6]

great work man..thank you for such a beautiful video and explanation

[@m0nty90]

great footage, thank you for your passion

[@kevinchang2]

Look at all that turbulent flow too fluid dynamics😍

[@jimsagubigula7337]

Light is so beautiful and complicated at the same time.

[@namithacibi6364]

You just made it crystal clear😍

[@22Tech]

thank you! we were learning about this in physics class but i wanted to see a visualization and this was perfect!

[@userr_aa]

same here man, the information in the book are quite scattering, I need something more clear to understand this more. Alhamdulillah, I found this video!

[@xelaxander]

Thanks for taking your time. The vid came out pretty well ;). Have a good time sailing!

[@drewendly89]

Sometimes ill sit and stare at the colors while washing my hands. I work in 3D and now I realize why IOR and film thickness are the two parameters for the thin film effect

[@robestivill5438]

Extremely nice video! Thanks for posting! (I also work in microelectronics and came here after photographing some bubbles) :)

[@TheWTFcakes]

So freaking cool! Thanks for the explanation, ive always wondered about this!

[@sonatinac8514]

Very helpful,I literally find all over internet to see why the bubble is black or transparent

[@manakparmar1793]

Best visualization Thank you sir 👌👌😃😃😀

[@55Ramius]

Really nice video. Up close and slow motion in parts or freeze framed plus good explanation. Good job. : )

[@SocksWithSandals]

Great video of this beautiful phenomenon.

[@rishusmathematics1992]

Its helpful video for me...bravo!!

[@vsr7517]

Awesome explained ❤️

[@kaladeosamari778]

3:56 starts to look like the beginning of a Mandelbrot set zoom. Haha

[@sheryllavigne9582]

A really great explanation ! Bravo !

[@mensageir0_d0_futur0]

Genius. You managed to recreate the universe. All planets and stars are hollow inside, they have an inner abyss.

[@rashidmohammed3341]

Great video. I really appreciate that ✌️✌️✌️. Informative. Could you please explain why camera lens have that coatings

[@MonteFleming]

Thanks for this video--beautiful shots and a great explanation of the physics.

[@navlalli88]

Physics so fascinating ❤❤

[@sheikhsaimaalavieasha8557]

VERY INTERESTING............THANK YOU

[@malanihome2121]

This video is awesome

[@snrnsjd]

2:03 the other way around. Thicker at the top and thinner at the bottom. :)

[@maxbernard426]

Thanks for great video... i show it to my Advanced Higher physics classes in Scotland

[@louisezero31]

Thanks for this amazing video!

[@ddeb]

Thank you very much for the video, I have linked your video in one of my video ... thanks again.

[@thaisbarbosa5048]

Great job!

[@omsingharjit]

Very informative

[@penpcm]

So you can till the life of the bubble by it's colors, the colorful the bubble means younger and the older it gets less colorful it become!

[@usamajamil1683]

so cool it was

[@edu_in_iitg]

Thank you 😊

[@mvfazio]

Great video! Such a cool visualization of thin film interference and great work explaining this phenomenon. I'm still pretty confused though about the white and black bands at the top. I get the black band (because light reflects has a phase shift and causes destructive interference), but am really struggling with the white portion. Any explanations are welcome!

[@hrishikeshingole5625]

Can I get to know more about your research Sir?

[@luke01112121212121]

Great explanation

[@chowchow6536]

can you please help me understand if the ray of light you meant here is a single wave or direction of certain part of spherical wavefront(plane wavefront)?

[@NicoleWestbrook-c5j]

How did you create your 2d soap film? I would like to demonstrate this to my students. Thanks!

[@HarishSasikumar]

Nice and interesting video. However, I think, the Colours on the Wings of those insects which you have shown are not from thin film interference. Though, in a way, interference is there, it's not dependent on the thickness of the wing. Color is primarily dependent on the lateral spacing of "periodic Nano patterns". You can look up 'photonic band gap' to know more.

[@ezu8501]

this is wrong. why wouldn't you just google it? there are many resources and studies done on the wings of insects which describe the structures responsible for thin film interference that produce iridescence. butterflies for example, benefit from it to fend off predators or attract mates.

[@HarishSasikumar]

@@ezu8501 figures a, b and c doesn't seem like thin film interference. I didn't Google it because I work on similar topics. Then again, I may be wrong.

[@SMorrisRose]

Nice. I've spent some time staring at soap bubbles myself. Here's a question: why do we see all the colors of the rainbow but a notable shortage of green?

[@srirampatnaik9164]

Despite it having one of the highest ranges of wavelength in visible spectrum

[@illblues1072]

Satisfying, thank you

[@erawanpencil]

What's the song at the end? :)

[@ritan5643]

Cool Video bro..!! Can I know what gear did you use to shoot the soap bubble..??

[@pedrojunior982]

I would love to use your images to talk about thin film to my students

[@edu_in_iitg]

Thank you

[@surenpatwardhan4489]

Great and Simple

[@هذةصورةكوكبالمريخ]

Try a one ray of sunshine passing through a soap bubble

[@orangutan6982]

Why don't we see colours due to Thick film interference?

[@gaclass]

I've been waiting Thankyou

[@Darket33]

I saw you on the bubble 😂

[@geniegreentrees]

Color = Frequency "Color" is just a word to show us how Frequency repeats. Hence the repeating letters in the word: Magic circles. Our vision contains the color - the light shows us. It's only being seen by each individual viewer. (person) We are not people or bodies. We are Frequencies traveling and immersing. Light-speed inhabitants via these meat curtains. Puppeteers really. Frequencies communicate. Thank you for this rainbow heaven result!

[@VyvienneEaux]

The bubbles definitely do look exactly like a gas giant because the same 2-D turbulence vortices contributing to the gas giants’ appearance occur on the bubble.
