We are working on it,but it will take time, but the thing is we are living in an environment where it doesn't matter how things came, how derivation came, how does particular thing look but we see how much we score in, jee, boards, neet etc. This should be changed
Thank you so much! I'm teaching 10th grade astronomy online right now, this is going to replace the demos I can't do tomorrow (and go beyond - I need to find a large diffraction grating like yours for next year)
Ok This makes physics interesting again. For real, reading this in textbooks without images is so boring. IT IS A CRIME TO MAKE PHYSICS FEEL BOOOORING. +Thanks a lot prof.
Wow ! 👌 just loved it. Nothing can be more interesting than seeing, in real, a phenomenon 🤩 that one is asked to imagine or visualize & of course then memorize - the Indian way 😏
Thank you for the demonstration. It might have been helpful if you could explain what the colors would represent to those who are new to understanding what properties they contain.
You're right, Rita. There's a lot more context needed than just the demonstration. Those interested in more information might be encouraged to view my lecture segments 30.1, 30.2, 30.3, and 30.4
Great suggestion, Rio. In fact, I have done just that. See my lecture on the nature of the atom: th-cam.com/play/PLkRMGCE8BEtakj1jBWNgIJcdwprADiOzC.html.
When electricity is passed through H2 gases, they will disassociate into highly-energetic H+ ions (due to electrical energy) which will then releases the energy it got and then goes back to ground-state (lowest energy level). The energy released is what you see in the line spectrum as light energy... or at least that's what I understood
@@adilmohammed6897 I have all the 8 gas ampoules and a spectroscope so I verified myself. While the noble gases correspond to the standard lines, HNO have very different spectrums and H doesn't have only the standard 3-4 lines but a lot.
Look at here, my sample confirms the (a) situation. The molecule is ionized but not broken, the bonding of the two atoms is still there, that's why I don't understand how you manage to have a single atom situation. I use the plasma ball, maybe the molecular bond is ripped with more energy? images.slideplayer.com/18/6086017/slides/slide_32.jpg

Hope this helped.
It's help me alot🔥
i love you

you are a saint
Thank you!
sir, you showed a fantastic experiment - which is generally not available even in university laboratories. Thanks for sharing it to world.
Thanks, Vinod. I'm glad you enjoyed it!
Correct sir
“To prevent burning flesh” I can see why they don’t do this experiment in many schools

And I, a 11th grade student is watching 😂
It's one thing to see this in textbook diagrams, but to see it happen in reality with an actual professor explaining it is mind blowing!
Wish Indian schools should have demonstrated to students in this way so that everybody could understand.
you can be the one to do it now that you have evidence
Yes so that learning will be enjoyable.

so truee.........
@Be the best same👋preparing for jee?
Even our physics teacher showed THIS video to show us what spectrum is. Thank you for this wonderful video
amazing. I´ve studied chemistry and even with master degree studying spectroscopy in 90´s that´s the first time I see how this works experimentally.
ew chemist
After watching this video, knowing which crystals to use for my lightsaber should be an easy choice now.
followed this to understand the black and white H-Spectrum diagram in my textbook, thank you so much!! i finally understand what it means!!
Black and white spectrum 😭😭😭
wow thank you for giving every confused student like myself to get to watch this instead of trying to imagine it.
These colors look so beautiful. Beautiful Demonstration as well. Thank you for helping.
Thank you Sir, I am using your videos for quite some years to explain concepts to my students. Very grateful
Thanks for the demo, this is exactly what I need to understand about the spectrum. Even I didn't have this experiment in university 😢
Excellent demonstration! Thank you for sharing.
It was amazing to see this experiment as I had only imagined about these spectrum.
Thanku sir for demonstration.

the best demonstration on spectra i have ever seen

I extend my sincerest thank you.
Great job sir

Thank u so much Professor ....
I'd watched tons of videos but not able to understand but now it's crystal clear...♥️
You are doing very fantastic work ,thanks a lot
Sir, Tons of Respect from India, for the clear demo 🙏
thank you! using this for distance learning bc I can't do the demo at school!
Who got this for their chem lab lmao
Wish I could have had more teach like you when I was in school
Thank you sir. Appreciate the great effort you put into making this video.Very educational
Thank you very much for making this amazing video. It helped me a lot in understanding the topic.
Thanks a lot...i am a grade 11 student..and i could not understand this through text book..this video really helped a lot ♥️♥️
same i’m in 9th

This experiment is amazing and very much helpfull for the learners.
Thank you sir , I am currently studying this topic , this helped a lot🙏🙏
Exactly what I was looking for, thank you
Thanks you for this demonstration.🙏
It´s amazing, the demostration help me in my studies!
Great never imagined i was doing this in school with plastic scale with tube light
Thank you for this amazing video and for ur explanation sir👍🏻👍🏻
Thank you sir
Actual concept clears by practical 👌👌👑👌👌
I m overwhelmed.....😭😭👍👍
Thank you sir the experiment cleared lots of my concept
This is just amazing, thank you!
I'm stressing because he's handling the container of mercury without protective gloves :O BUT! This is video is mad helpful. I appreciate youuuuuu!
Exactly what i needed!
Thank you that was a beautiful demonstration.
I personally liked it too much and found it very much informative !!! 😃😃😃
How can a bulb emmit continuum spectrum, if light is always transmitted via photons with quantified energy?
This is amazing to see it happening in reality 👍🏻👍🏻 thnx for showing
Such pretty lightsabers haha. So awesome. Thanks for this demonstration sir
Thank you so much sir that's why i am subscribing you
Thanks a lot sir. U R DOING A GREAT JOB.
this makes so much more sense thank you
Wowwww wonderfull physics!❤❤❤
Really Amazing I am amazed to see it .thanks you so much creator :))
Thanks sir for ur efforts😍✌️
sir can you pls explain why there is also a band of just blue on extreme sides of rainbow band at 1:50
4:00 I thought nitrogen will produce blue glow instead yellow ?
Bro if you remeber that nitrogen oxide flames always colored yellow so you can relate....
A student of class 11
Practical knowledge. Thanks sir 👍🙏🙏
Really adorable work
this is so beautiful thanks for sharing it😍🤩
Such an interesting class
Amazing colour
Thank u sir for this fantastic experiment

Thank you so much Dear Sir
How can the thin diffraction gradient act as a prism?
Thank you very very much sir......
This is so helpful. Thank you!
Thank you so much. Can you give us the reference of your lights? We're can we get them? I'm physics teacher in France!
I have hydrogen spectrum in my 12th grade curriculum. That is why I have come here to understand it well from india.
Wonderful video
Thank you sir
Really amazing sir 🙂
5:17: how can you have single H spectrum instead of molecular H2 spectrum?

Thanks professor.
Why the spectral lines are appearing on either sides
Amazing demonstration! Where can we find this big, diffraction grating?
Is the mercury a gas or a vapor suspended in the tube? Or is the liquid mercury glowing?
why is it called absorbtion spectrum. What absorbs what?
Wow it's very wonderfull, excellent
Sir,is the spectrul line width is dependent on temperature of the given gas?
Awesome, thanks
Your experiment is osm sir
gonna tell my kids that these were the lightsabers when we were kids
What's the name of those bulbs? Thanks!
Sir,why is the width of certain colors more than the others?
May be it depends upon wavelength
That's pretty neat
Can I use this video in my class where I'm servicing as a teacher at college level in Bangladesh?
so beautiful
Here Emission spectrum means type of Atomic or line spectrum... Am i right? Plz tell me ... I've a lio confusion
Thanks
what is the limitation of this experiment?
The violet line in hydrogen spectra is just like lightsaber of mace windu
Can anyone please explain why those spectrum are mirror images in right and left ? Why not same sequence
Sir why elements like neon show only reddish+orangish colour only why dark spaces are there
Why are you so good
when we heat a solid or liquid it emits a continouous pectrum but when its is a rarefied gas it it emits only certain wavelengths why is it so?
thank you so much that really helpful
