What is Quantization of Angular Momentum? Magnitude & Space Quantization (of subatomic particles)
Вставка
- Опубліковано 19 вер 2024
- Angular Momentum plays an important role not only in Classical Mechanics, but also in Quantum Physics.
However, many times students find it hard to keep track of the different aspects of angular momentum in Quantum systems, more specifically Quantization. There is Quantization of both direction and magnitude of both Orbital and Spin Angular Momentum.
What is Quantization of Angular Momentum?
What is magnitude Quantization?
What is Space Quantization?
In this video, I discuss all these things..

Sir 🙋 I have a question.
As space Quantization depends on L and L depends on n. So if n has higher value , L could have
more possible direction. So can we say that if n approach infinity L could also have infinite possible direction. Further, Can we say that at highest n value L is not quantized.
If so, can we relate it to macroworld like that of earth.
@@tarabhatt8082 as n increase, radius also increase and no. of possible L also increases but value of ml always varry from -N .....--1, 0 ,+1......+N in purely discreat manner in all situations.
Example- say n= 10then l=0,1,2,3....9
For l=0, ml= 0
For l=1,ml=-1,0,+1
.......
For l=9, ml= -9.....-1,0,+1......+9
Similarly you can think for any large value of n or L.
Hence here you see discreatness is not going to break however large L may be.
Remember this is not like Bohr energy model which looses discreatness as n goes higher and higher.
Thank you sir.
This topic can not be taught better than this. Thank you so much sir
Wow! I wish I had seen this during my physics bachelor's. It all makes sense now. Can't believe it took so little for everything to fall into place... Glad I saw it now, though. :-) You're amazing. Keep it up. Kind regards from Sweden
Great efforts 🤗🤗🤗 we need people like you you are truly doing a great job
Thanku :)

I took Quantum I and Quantum II in my undergrad and never fully understood this. I just knew how to calculate things. But damn, you just connected everything I already know. I can't thank you enough! You, sir, are amazing!
Study with such a huge knowledge, this proves that we don't need fun during study, just good examples and way is enough.💕💕
Best of best lecture on orbital angular momentum and magnetic quantum no. The way you showed different orientation is awesome..100% visualisation clear ... I don't know whether you are senior or junior to me, still accept my Pranam...
Excellent Lecture.. Thank you Sir 😊
Wonderfull explanation sir .... while listening your class mind is fresh and peacefull...complete subject👍...thank you sir...😊
Wow. Very great lecture. I am studying physics for three years in Germany and this is the first time I understand the topic, because your explanations are intended for humans and not for robots as here.
Explanation no. 1 👏
Communication skill no.1 👏
Keep it up respected sir
Thank you 🙏
Sir your lectures makes Quantum mechanics easy to understand 🔥
Your clear explanation means that you love physics very much as the name of the channel .. Thanks a lot.
Concept completely cleared.👍
Thank you very much for the effort you put into this video. It was great. It is the best lesson on "spin" on UA-cam or anywhere. I will view your other videos.
Oh my god just to the point without any confusion.... Lots of respect.
Thank you for such a clear explanation!!
Thank you so much I had been searching for hours finally I understood this concept from you . Thank you so much Sir. It would be grateful if you give one more further lecture on this part regarding coupling of momentum.please I request you!!
After du exam....I am exited to read physics....because of you.....I am very lucky I find you....sir... thanks sir for such a very good effort
Excellent presentation and explanation that even a dumb person like me can easily understand. The ways you link the associated mathematics to the presentations are second to none. Well done and thank you for your efforts.
I found that sir... your channel is the best channel to clear all the concepts of students . Thank you sir 🙏🙏🙏
I felt like m watching some web series just curious for next episodes. U made it so interesting. thanks sir 🙏😇
sir,
I was studying this whole vector atomic model all on my own and making detailed notes from every possible source, diagrams, illustrations, and gifs showing how things move. and now at the end of the day, I found this video. while studying I was talking to myself like I was teaching and was imagining the same images I 3D. now I feel so confident to watch this because it's like adding a constant c after integration. as if it just settled everything right into mind palace and it is never going to vanish now. ....
beautiful and highly helful. thinking you,
Your channel should have more subs.great effort ,nowdays there are no teacher like you
Outstanding Lecture Sir 🙏.Thank you sir for your effort ,this lecture is very important and helpful for Atomic Physics and Nuclear Physics. Thank you Sir 🙏.
Struggling to understand the concept and diagram for a long time. Thankyou.
Very nicely explained , making my concepts more clear just can't thank u enough sir......
Great....Great...Great Sir !!!
incredible explanation. You clearly have a crystal clear image of this subject. This playlist is literally the first playlist I am watching on the topic of nuclear physics and wow!! Much love
Fantastic explaining of angular momentum
So good to know that there are such good teachers in India
really a human material rather than robotic material
thank you so much you clear my concepts which i was struggling a lot during my bachelors
Nice explanation just teaching like a wow❤
Do you even have slightest idea, how brilliantly is this topic taught by you? Oh my god.....❤️
Oww such an impressive teaching and fluent english
amazing !!! you really explain very dificult concepts so well !!! im in the last years of physics carrer and your videos help me a lot. THANKS!!
This is the best video of physics lecture I have ever seen.
Thanku so much sir ,for such a deeply explained video. Keeping our love for physics alive.
Very coherent and well presented lecture , thank you.
This guy's a genius!
Sir ur explanation is awesome..... Bt it will be more convenient for us if u will explain in our desi language....... And thank you so much sir
Really ur love towards physics is noble
Sir,Mai aapka bahut bahut aabhari hu.....mujhe aashchary hai ki aapki har ek bate mai itni jaldi kaise samjh jata hu!!!
Thanks for explaining the basics more visually and not just jumping into hundreds of formula.
Thanks for uploading such a great video
You are an excellent teacher.
No words to express the respect for u legend. 🎩 off
Some people really doing great work fir others.aur unme se ek aap bhi ho...Thanks a lot.god bless you
Thank you so much :)
I think that there no any better explanation techniques than yours sir. I'm in love with your videos and your explanation techniques.
no words for the quality and pedagogy of your lectures sir...thank you from the heart ..teachers like you are god fayhers for we students .please keep uploading more lectures sir👏👏👏👏
This is the best lecture of physics i have ever listened to 👍
No particle spins on its own axis, physically. It's a misinterpretation in textbooks to distinguish between orbital angular momentum. It should have been intrinsic angular momentum. Its nice you have explained it
Sir, you are so nice.
Your way of teaching is awesome.
Super explanation I really understand the angular momentum concepts
Absolutely great efforts.Nice teaching method i have ever seen.thanks a lot.please make videos on other branch of physics such as quantum mechanics ,classical mechanics,electronics etc.
Finally the concept of A.M is cleared .....Thanks sir u did a great job
Thank you for such great Explanation !
Osmmm🥳🥳thank u so much sir
Wow! That was a fantastic explanation. Possibly the best video I’ve seen on UA-cam. Very talented educator.
You are amazing at teaching, please make more videos, thankyou for all the videos till now.
Thank you and welcome:)
First time in you tube. Full explanation 👍
this topic was making me mad but suddenly everything fell in place....wow amazing!!!..Thanks a lot sir!!!
I can visualise it will be possible for the electron to change rotation in clockwise and anticlockwise for the angular momentum to change sign + to -. Sir may correct me if I am wrong .
You clear my doubt about space Quantisation...
WHAT IS QUANTIZATION?
no one explained in this form till now
Whenever teacher came up with this topic they just wrote down the equation or some formula and said this is so called QUANTIZATION.
Your explanation is 🤯
Why is this channel not yet famous??
Nice explanation.
Great video. Just started a book about quantum physics for the first time in my life and that vide helped a lot in understanding it better then just by plain text thanks a lot :)
meaningful Learning ..thank you
👌 this is the best youtube class for physics. Thank you so much sir, for your effort
Thank you professor 🤠........one of the best explanation on whole UA-cam
Great lecture and beautiful drawings!! Thank you!
Amazing! Very well organized! I watched this video without stopping!
Sir Sir I have no words to say about your Excellent Excellent Excellent explanation teaching method of teaching Sir
what a class...thank you sir
Thank you so much for your time and efforts 😊💕💗❤️
Great video! This was super helpful!
One of the best extraordinary teaching.
Sir i want your all lecture on All courses of physics specialy MMP EMT Quantum and in all such courses which play main role in physics....Thanks
An extraordinary brilliant teacher!
Awesome tutorial Guruji.
Thanks dost :D
Very very good explanation thank you sir
GREAT TEACHER FOR NUCLEAR PHYSICS
Flawless explaination...
Thnks soo much sir...how easly u explain this...
for the love of physics suits the dedication of this kind teaching.
Great sir. Your video is very helpful. Now i am able to understand. Sir plz u explain stern gerlach experiment
Enjoyable lesson if it was not because of the love of physics i would have got retake in digital electronics thanks
The lectures were completely clear...thank you sir
Excellent and easy to understand basics 👍
Great videos. Thankyou!
You are great teacher sir
Sir I finally understand what is angular momentum
Thank you so much sir after a long time I understood about angular momentum
At 23:42, the visualization may be not right, I think. It could be a clockwise rotation and a counter-clockwise rotation for both space quantizations (+1/2 and -1/2) of Spin Angular Momentum. But he showed just 2 examples of the space quantizations of the Orbital Angular Momentum (of + and -)
had this video available before five years ,i would have decided for higher studies. during my msc {chemistry} i was always fascinated/terrified by only one sentence ,precession frequency .
Very underrated channel
It's really a great lecture...
