The Stefan Boltzmann Law - A Level Physics

Instead of referring to brightness, astrophysicists tend to look at a star's luminosity. Stefan Boltzmann law tells us that luminosity is dependent on a star's surface temperature and its surface area.

I love what you do. May the force of the yt algorithm be with you!

[poohjj]

thank you for all the help! your channel should deserve more attention fr

[Chxxvo]

Thank you so much for this.
Very clear and easier to understand.

Thank you for this. Some people teach others that the area is just area (πr²), it should be the surface area of the sphere (4πr²) so it really got me confused.

Really good explanation of Stefan Boltzmann's law

[huzaifaabedeen]

you teach better than jee teachers in india

Interesting content ! Was searching something like this only!! Really loved it!! able to understand it in one go!!
💛

OH! thank you so much, i can understand it easelly now 🔥💯

[citrarizqin]

Thank you very much for the explanation! Great video!

[chapers]

Nice and efficient snappy video thank you

Hi❤.

My memory took a nap lasting maybe forty years and YOUR VIDEO is helping a total recall.

I thank you😂🎉❤

[tychophotiou]

My God that background music/noise was so annoying. I couldn't manage to get to the end of the video!

[SWATHY]

Amazing Videoooo❤💙No doubts.Thankyou VT physics so muchh🤛🏻

[roqaya_]

That's really helpful, thank you

There is always a mix between the equation presented in this video and the one that is in other areas, where they talk about how the radiant emittance(or something) is directly proportional to the surface temperature. What's the difference, and which one is the real one?

VT Physics: Thanks for watching my video and if you think you learned something from it be sure to subscribe
Me: Aight fair enough

The Stefan-Boltzmann constant and law is valid for ideal, so-called "black bodies." This video seems to assume it applies equally to all stars. is that a valid assumption? Based on my long-ago physics classes I think that stars may have emissivity close to a black body's 100% but not exactly. Please correct me if I am in error and exlpain why.

Why is the temperature to the power of 4

[mathadventuress]

Instead of saying Stefan Boltzmann constant every time it’s used consider just saying sigma
