I am a 79 year old retired mechanical engineer and am thoroughly enjoying your lectures, if only I had had you as a physics teacher I may have changed to physics! Thanks
Any advice for a young graduate engineer? Would love to have even a fraction of your experience and knowledge.
I am a recent mechanical engineering Graduate. Can you please share an ounce of wisdom on how to succeed in this field? Much appreciated 😊
whoever made that intro thing, should become an ASMR person, that was so satisfying to hear ngl
anyway, I'm here because I'm studying for a chemistry test on Atomic Spectra & Energy....It's High school IB-SL Chem...WHOOO (im bad at it)
Anybody else perfectly understands stuff, and then the second after gets immediately humbled and forced to watch a section for the 10th time 😂
Amazing, this tutor loves chemistry and it shows
Absolutely well done and definitely keep it up!!! 👍👍👍👍👍
Outstanding lecture !!!
I easily absorbed the 46 Minutes of lecture. It was this good!
Haha
Is it likely that there is an energy level for for the hydrogen atom En=-1.00×10 to the power -20
I am interested. Keep it up!
I have HCFC in the form of Blue Ribbon coin conditioner. It says it is harmful to the ozone as a warning on the bottle. I only used this on nicer St. Gaudens and Double Eagles.
How MIT conduct online exams?can you upload videos regarding this?
was he using rydenber's equation for question asking about 639 wavelength?
fantastic !!!
AWESOME!
When in doubt divide by 2π
In Einstein's Photo Electric effect experiment how can ejected electrons be both quantized AND linear???
What do you mean by linear?
Hydrogen have only 1 electron. @38:00 How electron drop from n4 to n3 and release red light?
It's not Hydrogen. It's hydrogen like ion
@@lisa7286 thanks. u r right!
drop of hydrogen electron from n4 - n3 would give red light of 639. If you need picture look at 28:37 depicts what I am saying in move from n2 n1 similar case light would have it's own light emission though. hydrogen does have 1 e- but that e- can be at different states n=1,2,3 etc. anything passed n=1 ground state would be an excited state.
but his answer was 4->3
red light in Hidrogen with 1 Proton is cause by 3->2 transition
you can look into Balmer series.... & 5.111 Lecture 5:- Hydrogen Atom Energy Levels
I understand that constants have a value that does not change but how are constants determined in the first place???
As fas as I know, it’s calculated with all the formulas and derived. I.e the g for gravity is approximately 9.81... deriving it from newtons second law.
Mostly from experimentation. Like E = hv.
Here people know the frequency, experiment to get the energy and then they can calculate the h.
h= E/v.
Similarly C (speed of light) was found out thousands of years ago by experimentation in India, Greece and yet more places
at 38:00 he did a small mistake
transition should be 3->2 [Balmer Series]

Where would solid-state chemistry be without physics?😎
China is still releasing a lot of CFC to the atmosphere.
didn't get anything
I think you need a little bit of high school chemistry refresher
if your talking about calculations I get why he skipped a lot of steps. and didn't show calculations.
the question is what do you even wish to get? (lousy hooman)
