Understanding Ultraviolet Catastrophe & Planck Postulate | The Birth of Quantum Mechanics

Max Planck's explanation gave him the Nobel Prize in Physics and earned him the title of Father of Quantum Mechanics. In this video, I summarize everything you need to know about the Blackbody Experiment.

Blackbody radiation is the energy emitted by an ideal object called a blackbody, which depends on its temperature. Scientists tried to explain it using classical physics, but the Rayleigh-Jeans law failed and predicted an infinite amount of energy at short wavelengths, known as the ultraviolet catastrophe. Max Planck solved this by proposing a new model based on quantum mechanics. Planck's theory suggested that energy is emitted and absorbed in discrete packets, called quanta, which formed the basis of quantum mechanics.

Please listen very carefully, folks. You can waste your time reading any text or watching any video, introductory or otherwise, on blackbody radiation, but this one is the very best. Don't waste your precious time looking at anything else. This gentleman is the very best. This is not meant to be a criticism of other authors/presenters/professors. No. But, there are some people - very few indeed - whose knowledge and depth of understanding is such that they can communicate the fundamentals and even complexities of very difficult subjects in a concise and yet thoroughly understandable manner. This gentleman is one of those people. God bless him for he has blessed us!!!

[@loveyouzindagisunny]

I started my third year from your lecture series sir....!!! It is very much interesting and conceptual Thanks Sir...

[@aafeer2227]

REALLY. If you make a PDF I will buy it, and probably I will not be the only one. Well designed, brilliant accomplishment.

[@Zack_Raheem]

Wow, the quality of the lecture is exceptional.

[@Sol-En]

Thank you ! For the first time I understood Planck's idea. It seems to me that this is even easier to explain if we say that with increasing frequency, the energy per degree of freedom is greater, but the number of degrees of freedom themselves are getting smaller and smaller, so the density of energy tends to zero. And in the classical case, the number of degrees of freedom of the electromagnetic field did not decrease with increasing frequency.

[@lizashabnam]

An amazing lecture of Quantum mechanics I've ever seen.❤ huge respect sir🙏

[@hidhashahinpk6864]

your explanation is very neat and crystal clear. Thank you, Sir

[@terrifictiger]

Explained with so much clarity. Thank you very much

[@aafeer2227]

Simply the best explanation I ever heard.

[@ridhikachhabra]

Please make a video on string theory sir🥺

[@gotv6879]

Brilliant !! the best video on this topic .. thank you

[@KhalidMehmood-if7ii]

Very brief and lovely explaination

[@faisalazizsadqal8374]

Excellent and well needed lecture sir. I am preparing my govt lectureership interview and your videos, helping me a lot,, keep the good work up ..

[@cesarmoreno987y]

You read my mind: I wanted a video like this! your content is amazing

[@user-ny6wh5yc1s]

Excellent lecture. Wish you Long live and prosperity❤

[@mgulley1999]

Best video on this topic. The key was the probability frequency issue that I didn’t understand.

[@marspalk7611]

Job well done on all lecture. Keep up the good work.

[@stuartgoldsmith2310]

Well explained thanks.

[@DPPPHYSICSCMSir]

Excellent sir ji

[@navskygupta5311]

Awesome lecture

[@ishvm1489]

Yes sir make a video on string theory...

[@gok_dogan]

Excellent 👌

[@anusriprasad8476]

Very helpful vedio sir 😊

MAN I'M HAPPY WITH Thermodynamics

[@rushikanagla690]

Thanks for posting such valuable teaching playlist for free of cost, others would definitely had made it a chance of earning by selling it ! U r unique Sir , with a hope that u would do the same even in future 😊🙄ur student

[@nafis2389]

Sir... I have a request... After Quantum mechanics.... Please please make lectures on General Theory of Relativity...

[@BOT........]

Already

[@sandeeppatidar1106]

Thankyou

[@sgandhi5925]

Sir, classically explained the failure of classical physics on Black Body Radiation

[@jamesraymond1158]

I finally get it. The ultraviolet catastrophe happens on the right side of the graph. Previously I thought it happened on the left because I thought the x-axis was wavelength, not frequency.

[@nickallbritton3796]

love your lectures and I think they're a great supplement to my classes. I have one question though. I plotted the planck energy distribution using desmos to see a qualitative graph and played with the constants a bit. I can never get a positive concavity for low frequencies which is how you drew your graph. The exponential is overpowering the quadratic. Going back through your video I noticed that you also have a dv in the expression, though. Is this an infinitesimal? How do I interpret this and is this why I cannot reproduce the correct shape? thanks for the video

[@k.utkarsh5548]

Idk y but you have a vibe of Sagar shah of chessbase India! He also has that same innocent smile on his face

[@ozadhruv1879]

Can anyone give me the link to the old video for stefan's law, wein's displacement law,etc

[@dakshatamandloi3535]

what does it mean when we say that the black body is in equilibrium with the environment with some fixed temperature?

[@amanprajapat9887]

Iit jam chemistry ka bhi kuch ho sakta h kya with top faculty, with topic specialist teacher 🥲❣️❣️

[@ashrafulalam8402]

Which one is spacing? Is it small blue rectangle or the difference between kT and small blue rectangle?

[@sankarshanharidasan6751]

Is it plausible that a distribution law have same differentials on two sides of the equation as in this Raleigh jeans expression?

[@prashanthramg9005]

cube shape was the reason for assuming 1/2 multiples of wave length from there the derivation of quantum of energy. so how can this be generalized...

[@physicsgalaxy9933]

How can posible value of energy is zero in quantum mechanics. n=0 then E=0 Why??

[@maheshrocks65-df2mm]

Choose Emversity for courses that blend theory with practical applications seamlessly.

[@user-sz5dt9ih7f]

What is "delopsilin?"

[@norvikvoskanian4294]

What happens when the thermal energy of the black body approaches its work function? Will the temperature stop going up for increasing dE and instead electrons will be emitted?

[@UmarFarooq-hs8iu]

ionization

[@norvikvoskanian4294]

@@UmarFarooq-hs8iu ionization of what? As temperature increases you get vibrational modes that release electromagnetic radiation in the form of black body radiation that follows Planck law. At some point the energy will be sufficient to release electrons from the atoms (whatever the material of the black body is). What is the signal for this energy in the Planck curve? Or is the Planck curve only valid for energies below the work function?

[@radheshyamsaha9204]

Sir, CSIR NET December batch kab tak me start hogi??

[@FortheLoveofPhysics]

It will start in June

[@puneetbajaj786]

Sir i have a question please reply, 😅 As range of electric field is infinite,do em waves interact with particles at infinite distance from the line of propagation?

[@BOT........]

Yes but , it's almost 0 but 0

[@hmmm1482]

1/r² on infinity converges to 0

Sir please thermodyanamic per bhi video daliye na please sir😂😂😂😂😂😂😂😂😂

[@sajidkhan6017]

Sir, I am from Bangladesh. I wanted to admit to your physics course but it's only eligible for Indian people only. Sir, I am requesting you to open for Bangladesh, it will help us. Thank you, sir

[@FortheLoveofPhysics]

You can login via email, and access, no issues. For any query you can whatsapp [phone]

[@BOT........]

U can

[@rohanlii3]

Sir please don't let us and must tech us

[@bhavikinfy]

He explains it well but the problem with his videos are too much mathematics. The common physics lover public is interested in the Physics part, simplifying concepts in easy language and not long mathematics mumbo-jumbo equation derivation!!

[@marspalk7611]

You need Math to understand in depth. All great physicist were great mathematician also. Good luck.

[@BOT........]

😂😂😂 mathematics is the language of physics.😅😅 Without math physics is over. You must know it.

[@kentykatele4353]

These are the best video on KZbin, he allows us to view how mathematics proves the theory in physics and the experiment.
