Specific Intensity: What's the Flux?

In this video, we examine why astronomers (and other scientists who care about light and radiation) generally use specific intensity, rather than flux. More material at casper.berkele...

Thanks! These videos are great for supplementing the basics in my astrophysics course.

Brilliant explanation. Thank you Prof. Parsons.

[@sepidehsepehri]

thank you so much for the great explanation

[@sulaganaacharya7863]

I have a deep interest in Astronomy...This was really helpful

[@JohnVKaravitis]

Excellent explanation.

[@MalaPokhrel]

Thank you for such a great explanation.

[@kotykvmer]

Thank you very much, this is great!!

[@JraKn]

could you do a video on the derivation of the momentum flux moment?

[@akarshrayu4753]

Amazing explanation!!!

[@aretew6373]

It was very fun and useful!

I have come across other authors that applies the term brightness to Specific intensity. May you comment please?

[@AaronRobertParsons]

"Brightness" generally means flux per solid angle, without dividing out the frequency interval. For example, the brightness of the sun includes all the contributing colors of light coming from the sun. In other words, specific intensity is brightness per frequency.

This was really helpful. Now I really understand the difference between flux and intensity.
