Kirchhoff's law of radiation | video in HINDI
HTML-код
- Опубликовано: 7 ноя 2024
- In this Physics video lecture in Hindi we derived and explained Kirchhoff's law of radiation which states that the ratio of the spectral emissive power to the spectral absorptive power for any wavelength for any substance at the same temperature is the same and is equal to the spectral emissive power for the same wavelength for a blackbody at the same temperature.

3:16 arre wah!
mai to bachpan se galat padhte aaya tha ki ENERGY Neither be created not be destroyed...
lagta sir ne naya law bana kar ye purane wale ko chnge kar diya
sir aap mahan ho
are ghanta mahan ho..
Oye atishbaazi chutiye, baad mei bola toh hai ki nuclear fusion ke karan. Jo energy atoms unstable atoms mei hoti hai voh nai aur stable atoms banatay hai jisse bahut zayda energy release hoti hai. Energy convert hi hori hai.
Pta hai nhi kuch, comment section mei gandh gholne aajtay hai.
Bhai thodi research toh kar liya kar kuch likhne se phele
abe fucking guy energy black holes me create hota hay from mass and radiation pressure, thoda padai karle ma bap ki ijjat bachale🤣🤣
@@ABCDEFGHIJX apologise for making this comment, but let me first correct myself. I was simply correcting the term he constantly used, "created," which is absolutely false because the law of conservation is universal and applies to all states of matter. Instead, as he correctly stated, nuclear fusion occurs in the sun, converting nuclear energy into light and heat rather than creating new energy. Now that let's get to your point, I want you to be aware that black holes "emit" energy owing to quantum instabilities and that the black hole itself radiates slowly. So, this is how I attempted to explain the difference between the phrases creation and conversion to you, brother. I hope you learnt it and you'll make your parents proud. : >>
Aap bsc krr rhe hai ?
At last very happy to see 1M :))
Best explaination... Thanks alot sirji..
Sir you are best teacher all ever❤️❤️
Sir ji you. Are awesome you just rocked it
perfect explanation..sir..thank a lot..
Hmmm
Nice there are much thinks too learn soo thanks too edupoint soo thanks
krichoffs law of heat radiation states that at any given temperature,the ratio of the emissive power of the absorptive power corresponding to the certain wavelength is constant for all bodies and this constant equal to emissive power if the perfect black body at the same temperature and corresponding to same wavelength .
Right
lots off love u and ur team....extant class
Sir your all video are owsome
Wow 1M subscribers. Congratulations sir.
Sir, according to Hawking radiation se black holes emits energy..
Transmitted ka matlab kya hai...
@@AmitYadav-cx9ww ek sathan se dure tk urja ka sanchrn
Bhut bhut dhanewad sir sem.clear
Sir please make a video on plancks law of radiation
Very nicely explained...👍🏻
bahut badiya.keep making.
+Prashant sahu
Thanks for support.
Your support is key for this channel.
absorptive powr and emissive power is not properly defined
Sir what is meant by creation of energy, will u plz explain.
sir ne law chnge kar diya h now energy can be created
for example:- sun to banata h sir bataye na
@@reyhann2012 sir ne nuclear fussion se energy bani kaha tha
Aur bhai har jagah exaplain karne mein ye bhi jaruri nhi ki convert hi kahe inta to common sense hoga hi jo bhi padh rha hai
Great explanation sir👏
Bhot acha sir
very good
sir please respect se boliye unko ...bahut great men hai please dont mind u
Challenge hat
You are right
Great Explenation sir
Sir , you are a classical teacher for physics
great explaination
sir why you kept wavw length as lamda + d(lamda)
Better explained sir
sir you are great
Sir bahut achcha h
+Manya Soni
Thank you very much for being supportive.
Your support is very helpful.
Very good concept
Loved it
Sir how to make note on this lecture . It is clear my doubt
Sala jo bhi aata hoga wo bhi ye dekh k bhul jaunga mai...Gjb Til ka tad bna diya hai .🎉🎉🎉
Osm lecture sir g.
Thank you very much sir for teaching from detail
Sir what do u mean by emmisive power nd how we define
sir ji krichoffs law in radiation good absorbers are good emmiters
Thanks sir 👍👍
Very nice sir
Well satisfied.....👏👍👏👌

8:00 sir then what abt Hawking radiation???
That's from black hole you genius😂, only stephen Hawking can explain that😐.
Thanks
Sir balck body ka emmisvity kya hota hai?
Sunny Singh For ideal black body its equal to 1
Awesome
Sir perfectly black body good observer but not good emmiter...?
Thanks sir
nice one
+Devender Singh
Thanks
Fabulous
Pata nahi pahle log naam kya soch kar kirchhoff rakhte the
sir black body heat ko emitted kyu nhi krta
It does emit, what made you think it didn't in fact for perfectly black body it emits same amount of heat it absorbs
Nice sir
maan le. yes maanliya sir lol
Sir plzzz planks radiation law ko proof kryn
Sir if you remind , energy is neither created by sun 😁😁😁
Wow.....
Why to assume emmisive power as e lambda ?
Because we are only considering light of a particular wavelength
Sir incident energy ko mass me convert kyo nahi kar rha hai please reply
Baki sab sab achhe se samajh me aya
Nobody knows if energy can be converted to mass. Let’s assume it can. Then by Einstein’s mass-energy equivalence, E=mc^2, just for 1 gram of mass, the energy required will be colossal. The energy absorbed is very minuscule compared to this energy, so it isn’t converted to mass
Sir at 3.34sec you tells about creation of energy by sun but the law says energy can neither be created nor be destroyed 🙄
👌
boss ♥
thus video is confusing
Sahi bikku bhai
Kirkhaf law
Korcoughff law 💀
Kirchoff's law states that
a) A good absorber of radiation is good Reflector
b)A poor absorber of radiation is poor Reflector
c)A good absorber of radiation is poor Reflector
d)A poor absorber of radiation is good Reflector
Which is correct and why plz explain
+Vijayant Singh
There is no relation between absorption and reflection.
Option (C) is given as the answer of this question (eg black body- it is good absorber but poor reflector),
but i think option (D) also satisfies this law (eg white body- it is a poor absorber but good reflector)
C and d should be correct
EduPoint really? Reflectance is inversely proportional to absorptance
Sir energy neither created nor destroyed ,par aap keh rahe hoki sun energy creat kra ra h.HOW?
Rowdy Rwt mass ko reduce kar ke
In the core of sun thermal energy come from nuclear energy ..
Rowdy Rwt,
Tum log chutia hi rahoge.
Mudde ko samjho.
cancept to thik tha but jo hona chaheya o nahi tha
Surya teri maa ki.
Kya nahi hai be isme?
Teri aukaat ke bahar hai sir ka samjhana. Edupoint is the best.😂😂😂😂😂
No one can beat him.
You go to hell surya singh.
Tatti explanation
ssss
Pura ka pura tatti explanation.. kuch smj ni aaya . Ar jo aata tha vo vi confusing ho gya
