Correction : At 20:26 I made a mistake for the trigonometric identity involving Sin2x. It should be Cos2x = 1 - 2(Sinx)^2 or, (Sinx)^2 = (1 - Cos2x)/2 FORTUNATELY, the final integration result (and normalization constant) came out to be exactly the same... So final result is correct. Uff :D
Comes from a chemistry with a lots of doubt on quantum chemistry the lecture was awesome doubt was clear and thank you again for the fluent English as i hardly knew or understand hindi thank you again appreciate so much bro
If not for Our Indian brethren what would we have been. Most of our lecturers make us to run to RUclips videos like this for help. And great you've done a very great Job Man. God bless you for us here in Nigeria ❤
I'm here to thank you for this lecture. This cleared all my doubts in this topic and I have attended all the question on this topic in my semester exam. Thank you again sir.
Thank you so much sir this help me a lot to visualise the quantum world...plzz make a complete separate playlist for quantum mechanics so to get complete visualisation....Again thank you sir Nd all the best for your channel....
FANTASTIC video! If you are here looking for a quick fix to your quantum well problem, please just take the time to watch this video. Explanation and walkthrough is phenomenal. This will help you with understanding and solution of more complex 2D systems as well.

This was an amazing video sir. I think it will be really helpful to students if you created a whole series of quantum mechanics, based on Griffiths. Prof. Brant Carlson has already made a course on YT, but I think that too lacks a certain rigour in explanation of complicated problems.

Let me share personal experience after beging remail till the end of video I quite unable to finding any single moment or second during I not enjoy not learn vai this beautiful video this thosand thosand and thosand time better than following any book for understand this topic I totally flat on your way of quite simple explanation of any hard topic its absolutely unique and finally I suggest if anyone who wants to learn, visualizes this beautiful subject follws this awesome leacture serious vai channal of for the love of Physics
Sir... please make some videos for the topics of Quantum mechanics like ... Radiation,de Broglie hypothesis, Compton effect, particle diffraction...it ll be quite helpful. During lockdown,clg off.so.. please sir i m requesting u...to make some videos for the given topics. Please sir.
Sir please make videos on atomic and molecular physics..... Sir ur lectures are very interesting and I haven't find such a good lecture like u even in Delhi university
Sir, as the particle is moving inside the box then it must have some energy and if we some how calculate it's energy then we can calculate corresponding wave function. And if we are unable to calculate its energy then also it has some specific energy which is constant but it's wave function is linear superposition of all the above mentioned wave function.Sir, Can you please clear my doubts ;) And thankyou sir all your videos are the BEST.
Sir please book you want to suggest me to build this subject smoothly .. because the general solution of second order you showed me not given many books which is confusing because this kind of direct approach to derive something is confusing for me given in books so please sir suggest me a book now i have a grrifth quantum mechanics. .. but many things are missing like completeness theorem , many internation comes in doing derivation, to understand derivation .. please suggest me a good book .. atleast reply if you want to give an advice 🙏 i am preparing for an exam

Its ok sir
From ur teaching I realize lot about quantum mechanics so thankful to anna..... ❤
Spot it but thoughts its a different way as the answer came to be correct
Comes from a chemistry with a lots of doubt on quantum chemistry the lecture was awesome doubt was clear and thank you again for the fluent English as i hardly knew or understand hindi thank you again appreciate so much bro
Then how did you get the final answer correct?
This is hands down the best lecture on the subject on youtube at this level. Hats off to you sir, great job.
If not for Our Indian brethren what would we have been.
Most of our lecturers make us to run to RUclips videos like this for help. And great you've done a very great Job Man. God bless you for us here in Nigeria ❤
Watched a lot of explanations over 10 years.
This one is the clearest.
Sir you are an really an amazing lecture your vocabulary is so apt
Please make quantum mechanics videos as a playlist just like nuclear Physics
Your lecturer is always clear and more conceptual thanks you sir for your lot of hardwork ❣❣
I'm here to thank you for this lecture. This cleared all my doubts in this topic and I have attended all the question on this topic in my semester exam. Thank you again sir.
Bestest explanation one could ever give on this topic.....
First time in my life i understood 95% of the content in any quantum mechanics lecture thanks to you sir 😇😇
Thank you so much sir this help me a lot to visualise the quantum world...plzz make a complete separate playlist for quantum mechanics so to get complete visualisation....Again thank you sir Nd all the best for your channel....
