- 086 - Emission and Absorption Spectra
In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy. Scientists may use the emission spectra of material to determine the atoms or molecules contained within the material.

This gentleman explained things under 6 mins which my teacher failed to explain in 2 lectures.
😂
This video is the most compact video out there, the 5 min lecture seems very easy but you need to watch it more than 10 times to understand it if you're a beginner. Teachers generally skip the introduction of prism , and shining light. Thank you for this amazing lecture ❤️
I don't comment usually but I got to say this. You are way better than my useless lecturer and his lecture notes!
and hes fitter
I am ur professor using a fake account
Im ur school board. Now f*** off
la ilaha illallah muhammadur rasulullah
@@aryans2131 I am the education minister .. now screw off
Sitting here a little confused, while looking at positive comments isn't helping me out.

I hope this helps, found it on another channel.
@@bassett6479 Ask questions.
Energy isn't created or destroyed so the light wave that bounces off and the waves that arte absorbed by atoms have to do something. That something is to add energy to the atom (absorbed, the colors you don't see) or take energy out (emissions or emitted, the color you see). If you know the energy level of an element, when you shine a laser through it, you will be able to tell what element it is based on the combined energy of the element atom and the laser light, since energy cannot be destroyed. That's how spectroscopy is done I think. I'm not a scientist but I'm pretty sure that's how it works
The first minute of the video is the key.
That was 2 years ago, so basically you time travelled😂 , it's 2021, I'm sure you understand now
Wow, I don't think I can properly express how monumentally helpful that was to me. I don't learn very well from reading, I need visuals and clear language to understand things. Precisely what you provided. Thank you so much!
Beautiful job as usual, though on this particular crucially important learning milestone, it would be nice if you could "slow down", be more intricately descriptive, with slight pauses for (absorption) "pun intended". This is such an important step in understanding light, chemistry, physics, astronomy. It really needs to be driven home strongly. Thanks for trying to help us morons.
Sir, thank you for ALWAYS being there when i need you. like seriously, since i'm a freshman who needed some understanding about the lecture.. until now, a senior who is doing research for the final project. you were and are always there for me. clear and brief. you'll always be my youtube father :D
Hope your doing well out of highschool. I'm a freshman and I already completed my five hs credit classes last year and now im kinda taking a break but just I want to learn as much as I can and advance before I take more classes. I could be done for the year or take more so I don't have to much work next year. What do you think?
whose your daddy -- spank me harder
I just love it! You made me appreciate the spectrum even more. No physics teacher I know has been able to explain it so well. I really have some tears in my eyes.
Thanks
I was having problems with emission and absorption spectrum but your super simplified teaching cleared my doubt .....thanks a lot. ....!!!!
I'm Turkish and all the Turkish Chemistry/Physics YT channels either had no videos on this subject or had uncomfortably shitty ones(except for khanacademy-turkey maybe, but theirs was not as detailed as I wanted it to be). Glad I know a bit of English, I managed to understand your video, it helped me a lot. Thank you.
Great explanation, and the simulation was fun to watch. Didn't know there was software for that.
Do know what is that software name? Can you tell me plz?
@@josephjohnson576 omg thanks alot 💕💕
There’s software for everything
I am 9 years late hesitated way too much watching this video, give this man an award what a legend
Was really confused about what really happens in emission and absorption spectra untill I found this video😊
after watching this like 10 ten times, I finally understand (at least i think so) the spectrums helping me understand WTH they are talking about in redshift.
Very helpful thanks! [for your information this isn't sarcastic)
thanks dude!!! i thought i was dumb not being able to understand it... but now i know that my teacher couldnt explain it in right words
thank you sm! it takes me about 2-3 repetitions with the video to ACTUALLY understand but that is part of the learning process!
Your diagrams really help with understanding :)
THIS IS SO GOOD. For the first time i really understood how different objects possess different colours. Also the simulation in the end was v helpful. Thanks! :)
Thank you again for another great video! My professor linked this a supplementary video, and I found it more clear than the written lesson. Thank's for the easy explanation :)
This is super helpful, i didn't quite understand this and I have a test in this coming up soon, but now I do understand it, thanks alot!
what do you mean, i understood nothing
The usual concise, well explained clip. Terrific for NSW HSC Forensic Chemistry. Many thanks for posting!
Well....I gotta say......that was not only enjoyable, but also informative....thanks!
Thanks a lot for this very elegant explanation🎉..
Thank you so much. Your lessons are always so helpful.
Thanks, Paul!! I have a test tomorrow and your videos always help clear things up
This video should be watched at 0.75 speed
Yep ;-;
haha... the same thing i did
Thanks bro
So what your saying is....
Photons are intergalactic atomic cryptocurrency.
No need for unecessary words like "cryptocurrency". It is an atomic currency because it IS energy. :)
whut😭
my lecturer took 2 hours to explain the masterpiece he taught in t video ...Thank you sir
This was so helpful especially that simulation.
Thankyou so much
........
Thoroughly explained.🎉Thank u
Your work has been saving me as I study for my final. Thank you so much !!
Sir , you made me fall in love with science. thankyou :)
Great video! I have quibble with photon expression as particle since until detection the photon probability wave is essentially spherical from atom. A spherical bubble/ripple moving outwards and when you burst the bubble you get an electron of that energy worth of energy.
Man you actually explained this in a way i could understand i am so thankful to you
Very good explanation,. straightforward and clear. Thank you
Woah
My school teacher couldn't explain. My tuition teacher couldn't explain. You're great 😍
thanks paul great video
I really needed to watch this in simulator to understand.... Thanks ALOT👍👌
Understanding in a short time is always better. Thank you :)
Awesome thank you so much! Really well explained, easy to follow and understand
Brilliant! The visuals make it so much easier.
He states that light travels at different speeds when put through the prism, but the speed should be constant, however the energy changes.
Speed is constant within a vacuum. Speed changes within a medium.
en.wikipedia.org/wiki/Speed_of_light
Thank you so much well explained and diagrams really helped me visualise what you were explaining.
Gr8. Simplified explanation. Very nice.
I got it! Thanks a lot!!! You made my evening much more “clear” in understanding this process.
Very helpful and to the point. Other videos on this topic were too slow.
Beautifully explained. Thanks!
Very good video. I`m german but I still understood your topic. Thanks for your video because there are no good ones on this topic in german...
I read the topic in my book and didn't quite understand it. But this explanation is perfect, thank you!
This actually saved me from failing my final! thanks!
That is really helpful.......im studying the chapter for a year.......but could not understand.........why didn't I see this before???!!....thank you sir
One of my favorite sir😍
OMG, thank you for explaining. I finally understand this
The best explanation of this topic.
Thank you I actually have a final Exam on this tomorrow this was so help full
Wow, you are great at explaining things, thanks for the video!
I absolutely love your videos they are so helpful. I am so thankful to you 😢 idk what I'd do without your videos
Only high energy light like UV and XRay make an electron jump to the next shell - ionizing energy. Lower energy light like IR is absorbed by the nucleus of the molecule at energy levels corresponding to frequencies at which the nucleus vibrates.
this was very helpful man thank you
This was greatest
I really like it
Hope I could LIKe it 1000 times
Great explanations as always Mr Anderson!
That's was sooooooooooo informative for a short period of time, thank you.
Thank you sir .This is a great education video. I really appreciate your hard works.
great explanation, thanks prof
THAT WAS HELPFUL
Excellent explanation. Thanks.
thanks for the taking to time to produce this video to help others, good work.....Thanks.
Your explanation is great thank you
very good explanation
Awesome demonstration !!
Great video, cheers!
That was surely helpful 😊
sir you are precise to the point but it would be kind of u if you slowed down a bit becos for us it is for the first time where we are trying to absorb the concept .thank you
Extremely helpful
you are just simply great, just loved it. Thankyou so much
U r definitely better than my science teacher
This is really cool and understandable, thank you
Fantastically informative video!
This is so well explained, especially the simulation
Thanks m8, was really confused by this before
teaching an entire course that I missed in lockdown in 5 minutes.
Why does hitting it with electrons cause it to emit light? Electrons aren't photons, so I don't get why this would excite the atom?
And also, why would you get different colours in a continuous stream?
It likes when someone punched you so hard on your face. The electrons just push the electrons in the atoms (they are same charge so they will repel each other) out of its original state and jump up to excited state
Electrons and photons are interrelated
how? @@kylegallun9685
Just hit with any energetic beam or particles. Electrons are just simple easy to accelerate and gain energy.
I have learned more from u teacher!😍😍
Veryyy helpful thankss a lot lovee ur videos!
very good explanation.... before watching this video it was dark for me... 10x a lot...
Thank you sir, I've learned a lot from you!
Why does it give different colours of photons? Doesn't the electron want to go back to its ground state in one go? If that's the case it shud form a photon of only a specific wavelength depends on the energy difference between the two orbits...do the atoms absorb energy differently? Why does we get different colours
I found that very helpful. Thank you Mr Anderson and team. :)
nice I really enjoyed this video
Brilliant. Elegant and simple. Thank you
Oh this was so helpful to me! thank you!
And thanks for the subtitles, as it made it easy me to understand even though english isn't my native language.
Thanks you really made it simple it was good thanks once again
This is certainly quite helpful, but you go a little fast. I had to watch it a couple of times on a slower playback before I got it. Love it anyways!
Omg i struggled to understand it for almost 2 years.. now i got it easily! thank you so much! :-)
Best vedio ever
Wow, just wow! Thanks for your useful video
Great video, helped me finally understand this topic. The animation is very helpful. Thank you :)
Thanks for the animation..it helps a lot
This was very helpful!! thank you!!! :)
Sir actually I can't understand about the variation in ground state in different lines .
the ground state in Hydrogen should be n=1 but in Balmer series n=2
in paschan series n=3
and so on...
paschan
