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.

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.

That was a really interesting topic… Well explained!

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

[RaginiKeshri-jqrj]

Make more such concepts related videos. iam jee aspirants and it helps me lot to understand the graph of intensity, wavelength graph

[x_god]

Bro predicted the colab of Wolverine and Deadpool

[quak]

thaNKKK yOU .. very well explained.. and cool animation

[chrisbell]

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?

[nthumara]

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

Isn't hydrogen and helium plasma purple in color, with line spectrums?
If so, then how's Sun made of hydrogen and helium plasma?
Can we make hydrogen and helium plasma emit blackbody radiation?

So, if objects with greater temperature (heat) emit more intense radiational heat, then how might cold gases at 10, 000 foot elevation ein our atmosphere emit greater heat which might warm an already warmer surface? Doesn't this idea violate basic Laws of Thermodynamics?

Isn't a black hole a perfect black body?
