Would have been cool to add the different kinds of radiation that occur from the different movements, with their spectrum. Vibrations generate infrared light, rotations generate microwaves and translational energy generates radiowaves, etc.
@@zilit5434 IR spectroscopy is used to determine functional groups present because they excite rotational modes. They've even narrowed down specific vibrational modes of some functional groups to narrow wavelengths, meaning they can activate a specific type of vibration. Our microwaves activate rotational modes in water molecules. UV excites electrons enough to cause chemical reactions to take place. Translational energy generates radiowaves. It takes more energy to excite an electron than it does to make a molecule vibrate. It takes more energy to vibrate a molecule than it does to rotate it. It takes more energy to rotate a mulecule than it does to translate it. Photons are emitted by accerlating charges. Electron clouds are charged thus fluctuations in the cloud will generate photons. A vibration is higher energy than a rotation because a rotation can't whip the electron cloud around as much as a vibration can. IR Spectroscopy - infared UV-VIS Spectroscopy - uv NMR Spectroscopy - radiowaves Microwave Spectroscopy - microwaves GCMS - Mass If it's not about what movement is happening, then what is the cause for emissions of differing energies? What causes a low energy photon and what causes a higher energy photon?
@@MichelleHell forgive me I'm just trying to understand this better. Are you saying that certain EM waves cause kinetic changes, such as microwaves causing rotational changes in water molecules, or that certain kinetic changes create specific wavelengths of EM waves? Or both. And wouldn't higher energy EM waves cause a molecule to undergo that corresponding kinetic change as well as all the lower energy excitations as well?
It is simply impressive how you were able to break down such complex theories to the basics and using great visualisation so one can understand them. It really helped me to understand other topics! Thank you so much!

I am lost in words. Such a deep topic explained the most simple and elegant way possible. Light years ahead of other more popular science channels. Congrats
this channel always helps me internalize or learn a fundamental part of why something happens on something i thought i already knew alot about, for this video it was how white light from heat is simply because its hot enough to have enough combinations of different wavelengths of light for our eyes to pick up enough of those wavelengths together for our brains to interpret white, if theres anything i wish i could have it would be to see every wavelength and a brain to process them as different colors (and also a way to filter between different spectrums otherwise youd be basically blinded/overloaded with mixing colors)
Amazingly done, can't thank you enough with this explanation. I'm currently doing a masters on this subject and this is way beyond better explained than most articles and books.
THANK YOU! I was having such a hard time visualizing this concept in my head recently while watching other videos on physics and this was by far the best "dumbed down" explanation I've seen and now I really feel like I have a strong grasp on the concept!

Dude that was a great explanation of wave forms as they relate to electron orbitals. I've finished many chemistry classes in college, including molecular chemistry and organic chemistry labs. No one has ever explained to me why electron orbitals looked the way they do, thank you.
1. Why does the electron by changing it's magnetic field send "ripples" or photons through the electromagnetic field? 2. How does the electron change and why does it change momentum and wave function (what is a wave funciton?)? 3. Why is the electron in the orbital, also why would it change energy if it isn't in it? 4. What defines a orbital that makes boundary for the wave functions? 5. Why would the electron change the orbital? 6. Why do molecules vibrate with thermal energy? 7. Why does the specific frequency vibration stimulate the excitation(what do you mean by excitation?) of the electron in the higher orbital (why higher?)? 8. Why does the electron by returning to it's ground state produce light (also why does it return to its ground state?)? (so is the answer for the first one because it changed it's energy?) 9. How and why does the energy get transferred from a vibrating molecule to its neighbor? 8. What do you mean by the electromagnetic field wanting things to be pointed in a certain direction? (what is this force that wants to align the molecules a certain way and why?) 9. Why would the water molecule rotate when given external energy? (also how why does the energy change? what is it's nature and why is that it's nature?) 10. Why does the photon mediate a change in the electromagnetic field? 11. Why do the electrons leave the plasma and how do the detach from the molecules in that situation? 12. How do the electrons carry diverse levels of energy and how do they carry energy and in what form is that energy at all (also why are there 4 levels?)? 13. Where does the kinetic energy from colliding into each other and ions go (what form does it take?)? If there is someone kind enough to educate me please.

Even as someone with a general understanding of what’s going on behind the scenes it’s really nice to have all the gaps in my knowledge filled on the subject and in such a short video.
So naive... if by gaps, you mean endless voids, maybe. You, myself, all the geniuses around the world...can only ever hope to understand an insignificant fraction of what's "going on behind the scenes."
Guys keep doing videous like this. Your channel definitely have big future. Your channel is one of the best channel i ever saw on youtube. Your animations are awesome. I'm going to share this to all my classmates.
I watched so many educational videos and lectures about physics and astronomy over the last years but your channel is something else. You are a real gem to TH-cam and highly underrated. I hope you will get more recognition as you absolutely deserve it! I am so happy that youtube recommended one of your videos to me. I watched some your videos even more than once and looking forward for all the videos to come! Keep it up
I thought i understood black body radiation, this video pushed my understanding to the next level! That too, without using jargon. THIS is how to teach. Feynman, the greatest teacher of them all, would agree. More please!!
I'm not sure if you made these videos because you enjoy teaching, care that much about science, or because you just care that much about others; but good for you. Good for you for helping people be more by knowing more. There is no kindness, no love, no happiness without understanding. Giving people a greater one is giving them life.
This channel is truly underrated...The way of explanation is Extraordinary and very easy to understand...just WOW🥰🤩 You just earned subscriber bro...I am glad I found this channel🔥🔥
Dr. Robitaille is right. Most TH-cam videos about blackbody radiation are not really about the process that Kirchhoff and Planck wrote about. In fact the last 6 videos just used it as a way to introduce the concept of the quantum. Not one showed that the heated body was emitting a continuous spectrum.
Now, some people wouldn't believe me, but, as a blacksmith, i sometimes need to heat up metals to extremely high heats. And the thing is, most people will tell you that it starts glowing red, then orange, then yellow and then white. But what i've noticed is that when approaching the bright white color, there seem to be very subtle green reflections. Of course, at these heats, the steel gets blindingly hot, but still, i've never heared any blacksmith talk about green lights of black body radiation. And from the diagram, it looks logical, as green is right after yellow
"Bremßtrahlung" :-D :-D :-D :-D would be a really cool spelling with one of the most german letters. Unfortunately it's spelled boringly "Bremsstrahlung" ("brems(en)" = to brake + "strahlung" = radiation)...
@@supaproximalsix2155 Being warm blooded isn't an on-off state. It's a continuum. The stronger twords the warm-blooded end of the spectrum, the better an animal is able to regulate it's body temperature. A completely cold blooded animal would always be whatever temperature it's environment causes it to be. A completely warm blooded animal would always have the exact same body temperature. Higher temperature allows many chemical processes to happen faster. Including the reactions that cause your muscles to move. So if an animal can keep warmer than other animals in the same conditions, it will be able to move faster.
This is excellent, never have seen such a clear explanation. Thank you. Ps: the only thing missing was to explain why was there the "UV catastrophe" - maybe this could be a follow up video :)
DISCLAIMER! „Bremsstrahlung“ is written wrong. The ß letter is only used as a sharp s after a long vowel. It is not used s a replacement for ss, which is used as a sharp s after a short vowel, or happens to appear when two words are combined, the first ending with an s and the next starting with another one. But other than that, great video. I learned about sources for black body radiation I wasn‘t aware of.
Beautiful explanation about the reality happening in the background of every glowing object. One thing I want to know here, when we give energy to an object and excites its electrons or brings changes in its pre existing EM field, does this excitation causes photon emission ?? Or after the excitation returns back to its ground state, which is a stable state, photon is emitted in equality to photon absorbed during excitation..
The way he explained about the heat got me dying "the heat is the excess energy that a molecule or atom contains above its ground state. This can be represented visually as a change in rotation, vibration and location." I listened this again and again as no one has explained heat soo intuitively in my 9 years physics journey! Hats off!
I mean there wasn't any discussion of relativity or relativistic concepts in this video... He found a way to (hopefully) teach even idiots one of the fundamental principal of quantum mechanics, the idea that energy (light) comes in discreet packets or quanta.
Ian Malcom in Jurassic Park cited black body radiation as a reason for wearing all black even in heat. I always wondered what that was about. After watching this, his statement seems to make less sense. (Though your presentation of the material made perfect sense) Thoughts?
Hm, something I still don’t understand is how higher temperatures enable transitions between higher orbitals and the ground state. I thought photons have only a single unit of angular momentum, so you can’t transition between more than one orbital level at a time?
@@volbla QM model for atomic transitions has selection rules for allowed transitions, one of them being that a transition between orbitals of different parity (eg., s-to-p, s-d) involves a change in angular momentum of the electron. Since a photon can carry only one unit of angular moment, a transition can only occur when the change in AM is 1. So d-d transitions are parity forbidden, as are d-s transitions. Bohr model doesn’t consider orbital parity - the model fails to account for parity-based selection rules that have been experimentally observed
@@volbla yeah it’s…. Heavy. Explanations for spectroscopic transitions get complicated quickly when using quantum mechanical models… but lower levels of theory don’t fully explain most experimental observations.
@dzfz2100 Even though there may exist states between a high-lying energy level and lower/ground states, there may be allowed certain transitions which bypass those, thereby emitting one relatively larger photon.
I won't EVER get tired of repeating this: This guy is the next step in educational evolution.
His analogies are spot on. His animations, friendly, entertaining and not distracting. The way he organizes his speech, how he quantifies the ammount of info given each moment is perfect.
Maybe he is not concious about the educational theory behind his creations,,, maybe he is.... but nonetheless.... he is already mastering it.

Higher temperature allows many chemical processes to happen faster. Including the reactions that cause your muscles to move. So if an animal can keep warmer than other animals in the same conditions, it will be able to move faster.
@@lobsterbark thank you
This is excellent, never have seen such a clear explanation. Thank you. Ps: the only thing missing was to explain why was there the "UV catastrophe" - maybe this could be a follow up video :)
Bro I have always understood these concepts using these same shapes but have NEVER seen them properly animated. What the heck. This is cool
Impressive teaching, sir.
DISCLAIMER!
„Bremsstrahlung“ is written wrong. The ß letter is only used as a sharp s after a long vowel. It is not used s a replacement for ss, which is used as a sharp s after a short vowel, or happens to appear when two words are combined, the first ending with an s and the next starting with another one.
But other than that, great video. I learned about sources for black body radiation I wasn‘t aware of.
Beautiful explanation about the reality happening in the background of every glowing object. One thing I want to know here, when we give energy to an object and excites its electrons or brings changes in its pre existing EM field, does this excitation causes photon emission ?? Or after the excitation returns back to its ground state, which is a stable state, photon is emitted in equality to photon absorbed during excitation..
The photon is emitted when the electron returns the ground state, it's the emission of the energy that caused the excitation
The way he explained about the heat got me dying "the heat is the excess energy that a molecule or atom contains above its ground state. This can be represented visually as a change in rotation, vibration and location." I listened this again and again as no one has explained heat soo intuitively in my 9 years physics journey! Hats off!
i love your videos they are exactly what i need to visualize such complex phenomena
this guys a god, he found the way to teach even idiots relativity
I mean there wasn't any discussion of relativity or relativistic concepts in this video... He found a way to (hopefully) teach even idiots one of the fundamental principal of quantum mechanics, the idea that energy (light) comes in discreet packets or quanta.
Wow...How do you create these animations? they are exceptional!!
These videos are awesome. Keep it up.
Ian Malcom in Jurassic Park cited black body radiation as a reason for wearing all black even in heat.
I always wondered what that was about. After watching this, his statement seems to make less sense.
(Though your presentation of the material made perfect sense)
Thoughts?
Best video about science stuff ive seen in youtube
This video was so amazing, i think I'm gonna binge the channel !
*Where ru from miss?* 👀
Your animation and explanation is upto the point. Great work
0:20 "The quantum world; if you why enough times, that's where you will wind up."
One of the extremely few videos that i liked👍🏼
This video answered the question i didn't even know i had. Thank you
Hm, something I still don’t understand is how higher temperatures enable transitions between higher orbitals and the ground state. I thought photons have only a single unit of angular momentum, so you can’t transition between more than one orbital level at a time?
Pretty sure they can transfer between any two states, if i remember my Bohr model correctly. Why should their angular momentum matter for that?
@@volbla QM model for atomic transitions has selection rules for allowed transitions, one of them being that a transition between orbitals of different parity (eg., s-to-p, s-d) involves a change in angular momentum of the electron. Since a photon can carry only one unit of angular moment, a transition can only occur when the change in AM is 1. So d-d transitions are parity forbidden, as are d-s transitions.
Bohr model doesn’t consider orbital parity - the model fails to account for parity-based selection rules that have been experimentally observed
@@dzfz2100 Huh... Well that sure sounds like some stuff!
@@volbla yeah it’s…. Heavy. Explanations for spectroscopic transitions get complicated quickly when using quantum mechanical models… but lower levels of theory don’t fully explain most experimental observations.
@dzfz2100 Even though there may exist states between a high-lying energy level and lower/ground states, there may be allowed certain transitions which bypass those, thereby emitting one relatively larger photon.
