Blackbodies are one of my favorite physics concepts! Blackbodies are fascinating to me because of their unique physical properties and the crucial role they play in understanding the behavior of light and heat. These idealized objects absorb all incident radiation that falls upon them, regardless of wavelength or angle of incidence, and emit thermal radiation at a characteristic temperature-dependent spectrum. This property makes them essential in fields such as astronomy, where they are used as a reference standard for comparing the emissions of celestial bodies, and in thermodynamics, where they are used to study the properties of materials at high temperatures. I also appreciate the beauty of blackbodies' spectral radiance curves, which show a smooth and continuous distribution of energy that follows a mathematical formula known as Planck's law. Overall, the elegance and utility of blackbodies make them a source of wonder and inspiration for me.

Thank you so much for this video mitch

[@OSC1990]

My pleasure! There had been a mistake in the previous version of this video that was found by a student, so I made an edit and reuploaded the correct one. Thanks to everything for their support! Cheers, Mitch

Thanks a lot
Really helps a lot
Wish you were my physics teacher instead 😅

[@OSC1990]

I'm so glad I could help you! Cheers, Mitch

Happy I could help!

6:00 isnt this meter kelvins? instead of milli-kelvins

[@OSC1990]

Yes, I need to make an edit of this. Cheers, Mitch

Why couldnt we just use the luminosity and radius to solve for the temperature for star b? couldn't it be 6400 = (constant)*(4pi(6)^2)* T and get the answer from algebra manipulation?

[@nethra..s]

same question here !!

[@emilianosigales1443]

I thought the same, but I think he's doing it the way he is because he wants to get rid of the R(sun) and L(sun), and the only way to do it without knowing the actual values is by doing it like he does so that they get crossed out when dividing

[@douglasauyeung2274]

For the last question, when finding the surface temperature of star B, why is it LA/LB, rather than LB/LA?

[@fabiennedubois4983]

Have you figured out the answer?
