Understanding Black Body Radiation, Rayleigh-Jeans Law, & Ultraviolet Catastrophe - Quantum Physics

[@karthigamanivannan7922]

this video was having a perfect , clear explanation and i didnt even get bored at any point of this video. your way of explaining the concept was so good with full of clarity.

@9:31 Every next graph you draw at higher temperature, completely envelopes the curve at lower temperature.

Damn, this is the first time physics has ever left me in suspense! Hats off for the explanation Rishab sir! 🙏🙏🙏

Thank you for this, Rishbah. I've been explained blackbody radiation before, and I almost got. I understood everything except for the part about Wien's Displacement Law. That part slipped past me, but you explained it perfectly.

Very good explanation of black body radiation

[@atticuswalker]

as things heat up , they expand. when they can't expand anymore the energy density increases. Light redshifts with density. it's very simple

Sir thank you so much for this lecture.I find it hard to understand this topic but you've cleared my doubt, thank you sir.

[@xkguy]

Max Planck tried using a silver cavity. He got no blackbody radiation until he added a small carbon particle. He thought it acted as a catalyst. Dr Robitaille has shown that it was the graphite lattice that was actually required to produce blackbody radiation. This has led to his theory that the sun also has a lattice in the form of planar liquid metallic hydrogen (type 1) on its surface. Interesting ...right?

[@abhishekshah11]

Would like to see an appendix to this where the Rayleigh-Jeans formula is actually derived. Considering that the integration is instructive for calculus beginners and I'd also like to refresh my memory. :) Good work!

Sir , is a black hole a perfect blackbody/an absorber

[@ericwalters3426]

How can something absorbe, and emitt at the same time? Thats like having a magnet thats both positive and negative on the same side. Even electrons are positive, or negative, they cant be both st once. I guess like you say they dont exist in nature. I guess its really all theoretical then. Not sure what brought me to look into this subject, i think i was looking into scalar wave radiation, and i was trying to understand the different ways scalar wave radiation works.

A question : Why was it called ' Ultraviolet Catastrophe ' ?

[@TheSecretsoftheUniverse]

At high frequencies, at UV and beyond, the integral blows up. That's why it is known as the ultraviolet catastrophe. This term collectively signifies that Rayleigh Jeans law gives absurd results at high frequencies such as at the UV frequency.
