Understanding Thermal Radiation

In this video we'll take a look at thermal radiation, one of the three modes of heat transfer along with conduction and convection. We'll start by covering electromagnetic waves, the Stefan-Boltzmann law, black bodies and emissive power. We'll then talk about emissivity, absorptivity, transmissivity and reflectivity, as well as view factors, all key concepts for being able to calcualate the radiative heat transfer between surfaces.

Its unbelivable how these videos drop just at the instant you need them. Thank you so much!!!

holy fuck... i got goosebumps when he said "this is why object glow when heated."
i've never questioned why hot object tend to emit visible light.

You are an absolute godsend to all engineering students as 3blue1brown is to the mathematics community. These videos give the perfect overview for concepts that are initially hard to grasp with amazing animation and clear explanations.

[collegevibes]

Your videos are always a life saver come exam time. It's remarkable that you're able to explain these complex concepts better in 17 minutes than most professors can in weeks of lectures. Thank you!!

One of my favorite YouTubers ever. His videos cover essential topics in short time without leaving out important aspects of it.

[sadatiqbalpriom]

You deserve a million subscribers man. Before going to the nitty gritty, watching your videos for the overview always helps

Whenever I watch ur channel, I feel like why the heck did I not find u during my college.

[ashutoshsuman]

Your visuals makes it easier for us to understand. Thanks 🙏

[nonamex]

Your videos are a life saver for an engineering student like me. Before I even read lecture slides I check if you have a video on the topics, you truss and material sciense videos are amazing. Pls don't stop and thanks you

[alexdagios]

one of the most pleasent animated videos I 've ever seen, as an electrical engineer, i'm not very familiar with transfer heat concepts, but your video made it all very clear! amazing!

I wanted to learn 'what a blackbody is' when I clicked on this video. This video blew my mind away & I enjoyed every second of it. And oh yes, I also found the answer to my question

[bobvines]

Nice video and well explained. I wish this had been available back in the stone age when I was learning this.

Also, I wish there was a way to give a "thumbs up" & comments for your Nebula videos like the "Understanding Dimensional Analysis" video you mentioned -- it's quite good. I remember learning & using it a lot in college and at work too.

You are bringing a revolution to Engineering Academics and I feel I am fortunate to be alive in this era of revolution.
Our successors are going to be so much lucky, we aren't less tho.

Finally more thermodynamics, thank you!

[saturn]

I have no words to describe how good this video was. This channel is an absolute 💎 . Thankyou 💟

[alaminparves]

Even you don't know how much easy u make the topic understandable. Please never stop uploading new topics

[staircasefunction]

Dude I really appreciate your work. It doesn't matter to me what topics you cover in your videos but they're very easy to understand and interesting.

Thank you

[toninhosoldierhelmet]

alright, this was one of the best science videos i've ever seen

[siddharthmallbishen]

This video really cleared my concepts. A heartiest thanks to the team members of this channel.

What a coincidence, I just decided to learn about Quantum mechanics for fun, and this video is uploaded within hours, the graphics are so beautiful too!
