What is Blackbody Radiation: Explained in Simple Terms

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical because no object can be a perfect absorber of electromagnetic radiation. Think of it this way: when you heat an iron rod, it becomes extremely hot, and its color changes to dull red, followed by bright red, orange and then yellow. This is a good example of how black body radiation works.
In this video, you will learn about blackbody radiation, the blackbody radiation curve and how it helps to understand electromagnetic radiation and celestial bodies.

"Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler details Planck's thermodynamic analysis of the entropy of Blackbody Radiation, which motivated his frequency-dependent hypothesis to satisfy Wien's Law at high frequencies.
Planck's application of Boltzmann's Statistical Mechanics led to his conclusion that the material of the walls emit and absorb radiation in discrete quanta.
It's a great read.

Thank you so much sir ji.

I don’t understand why Wolverine was it the video??? Then Deadpool too 🤔

[@shem7146]

because the animator wanted to, it's not that deep

Where are you from?

[@shikharkeshari009]

That was a really interesting topic… Well explained!

[@djIIaSh]

so its the ether.... good job plebs

[@MessageFF07]

Great video 👍🏼

[@nthumara6288]

cah you do a vidio about calculations related to blackbody radiation

[@ZuhaLoveMusic]

Wonderful video. Thank you. I was wondering how black objects can get detected by telescopes, now I get it

[@spellman01772]

That explained radiation somewhat. And wavelength pretty well. But what is black body radiation? It's a huge deal in physics. Understanding black body radiation led to the discovery of photons, I think. And Planck's constant, I think. So, I came to this video hoping for more than: It is the radiation that comes from a theoretical black body.

[@markmcgarry6147]

It is basically our best approximation at describing black holes. We don’t understand it. Everything thrown at it is perfectly reflected. Heat in heat out.

Good job

[@user-zp1pk8br6t]

nice video sir crystal clear concept

[@Scienceabc]

Thanks and welcome

[@chrisbell7646]

So .... just to make sure I understand emissivity correctly.... the emissivity of a planet is how close it is to being a perfect black body radiator? Could you explain for example why earth has an emissivity of .61?

[@mikebar42]

Here in case someone answers 😅

[@lissettbonilla4847]

Excellent!!!

[@Scienceabc]

Thank you! Cheers!

Nice sir 2:30 ❤❤

Isn't a black hole a perfect black body?

[@reineh3477]

A black hole doesn't emit radiation. If they did we would be able to see them.

[@rahulsangvikar7973]

@@reineh3477 Black holes do emit radiation, called as Hawking radiation

[@krishnasree0113]

there's a lot of uncertainty when it comes to blackhole

[@markmcgarry6147]

@@reineh3477they do indeed emit radiation. And black holes are very much a perfect black body.

[@vanessacherche6393]

the bigger a black hole is the less hawking radiation is produced, the largest black hole is as close as it is possible to get to a perfect black body. maybe too close to perfect to be measured well. i wonder if there is a mass range of black hole that would be easiest to measure, i would guess less than stellar mass would be a good candidate for a spectrum
