Great job guys. Both animation+explanation. This is the need of this entrance exam era.. plz upload more tricky concepts of thermodynamics and quantum. You are going to be revolutionary soon if keep up your work.
According to Rayleigh jeans at longer wavelength in a box, the energy is high right? Then why does the graph have more intensity at shorter wavelengths
Rayleigh jeans doesn't explain shorte wavelengths & the graph also represents uv , visible region wavelengths could not explain because of shorter wavelengths
Rayleigh Jeans Law is for longer wavelength it fails to explain the phenomenon that happens in shorter (wavelength in UV, X-RAY and Gamma ray) wavelengths, I mean at shorter wavelength the energy increases continuously but actually it doesn't happen in real black body radiation after the Violet (end of visible range), Intensity of radiation starts to decrease, It's a failure of Rayleigh-Jeans law, For that you need to look into Planck's Radiation Law...
I still don't understand what is a mode? Some websites say that it is the number of ways you can fit a wave with nodes on the walls. So how does mode increase with decrease in wavelength?
suppose mode is like a stick. we have 1 box of length 1 meter and length of the stick is also 1 meter, then only 1 stick can be fit in the box; means 1 mode. let's replace the stick with 0.5-meter length, now 2 stick can be fit in the same box; it means 2 modes. similarly, replace the stick with 0.25-meter length, then 4 sticks can be fit in the same box; it means 4 modes. as the length of the stick get decreases, more and more sticks will fit in the box. similarly, if the wavelength of the wave is equal to the size of the cavity, then only one wave can be fit in that cavity. but the wavelength get shorters, more and more wave will be fit in the same cavity.
@@Fizica. so a mode is the number of ways a wave of a given wavelength can fit in a box with nodes on walls and not the number of wavelengths in a box?
Because we have used only one dimensional box. So only one way way to fit wavelength, that is number of wave. But in reality in 3D cavity a single of wave can be fit in many ways.

Sure....we are looking forward to start a new series for entrance exam
underrated . you deserve more ! :)
Exactly.
He's so talented.
Deserves more attention
Great video.now i am your subscribers

No if the wavelength gets shorter more no. Of waves can fit in a box. Then more energy...always wavelength is inversely proportional to energy...

@@Fizica. oh thanks
Nice explaination ❣️
3 mint sb smjha diya thankyou sir
Thank you for all your efforts, now this topics are cleared in my mind.🙏
You are amazing dude...it helps me alot...
Very nice explanation and animation too👌👌... Could you please tell that what is difference between modes and nodes?
I'm in love with the way u teach physics ! Really u r amazing
Best wishes from Pakistan ❤️
sar veri gud, bahut acha sa samaj aagya hamko. very gud *dear*
Very help full video 🙏
Nice dude ese hi banate rho..
Plz explain Compton effect
Badiya video baiya keep it up👍👍👍👍
Great video sir
Great job bro
Tq sir for a great explanation 👍
Kya hi khatarnak intro hai
Thank you very much Master
You really helped a lot. Kindly make a vedio on derivation of maxwell energy's distribution..
sure

exactly
@@Fizica. but in the video u said that one wavelength is equal to one mode, so i got confused.
Because we have used only one dimensional box. So only one way way to fit wavelength, that is number of wave. But in reality in 3D cavity a single of wave can be fit in many ways.
bahut aage jaoge
Great sir
Thank you so much sir 🤭
Kuch to chota hai lekin kam ka hai baki hum likh lenge bhai
Bahut accha hai
Thank you sir.
Thanks hindi easy
Aor sbki help krte rho
Best video
please can you transulate your vedios to make everyone understand
❤❤❤
❤️❤
👏👏🤘
