In this video Paul Andersen explains why light is important in probing matter. Light travels in photons and the energy of individual photons is determined by Planck's equation. Infrared spectroscopy is useful in detecting the vibrations within a molecule and can therefore give more information on the bond types. Ultraviolet and visible spectroscopy is useful in detecting the electronic structure of matter. Beer-Lambert Law describes how increasing concentration increases the absorbance of a solution.

Mr. Andersen, I cannot thank you enough for sharing these brilliant lectures with us here on RUclips. I'm learning a lot from watching your videos. Keep up the good work.
How is it that you explain in eight minutes what I was still fuzzy about after hours of lecture? You are truly an inspiration. I watch your videos all the time, simply to learn something new for the day. Thank you Mr. Anderson :D
Thank you so much Mr. Andersen! Last year your videos helped me get a 100 in Biology, and with the help of your videos this year I have a 98 in Chemistry. I'm planning on taking AP Chem next year and am so thankful that I have this as a resource!
I love your taste of music, Mr. Anderson!
Mr. Anderson: If we turn on the lights we can see solid, liquid, gas, and plasma
Time Crystals: Hold my 4th dimensional structure
I love your videos. really the best on the web. thank you so much
Absolutely interesting. Great video, very accessible. Thank you.
Mr.Andersen has made me the person I am today. He taught me the core values of life and that 50% of human DNA is the same to that of a banana.
Digital cameras. They capture a photograph using the light and then digitalize it giving us the opportunity to edit them in computers. Since light is matter, the digital camera copies matter and digitalizes it. What if we could make a digital 3D model from a computer to "get out" and take a form. It will occupy space. We will be able to touch it. The point is, what if we could take something from the digital world, to the world we live in?
excellent video...taught many things which we don't get to know by just reading...
by the way i have a doubt...
is their any relation between the length of the wavelenght of light and its crest or trough??
whats the ratio between their lengths??
can anyone please help me on this?
do not know !!!!!
Hi, my worksheet asks how many joules are in 1 mol of this amount of red light, do i just multiply avogrados number by the joules that is given?
Good Explanation, Keep Hardworking
sir i have light bit problem..
my question is that light is a matter or not ....please tell me soon about this....
nice explanation, I have got a specific question, if light is absorbed by solutions or matter in general, how come matter can vibrate light at the same time and make it visible to the human eye?, that doesn't make too much sense to me, there must be another explanation on how matter can get organized in such a process that we detect it as solid
Sir I want to know more about light and matter relation
Sir i have little bit problem in one concept...
my question is that light is matter or not....
tell me soon sir..??
Interesting because with sound waves it seems like the lower the frequency the more energy it has.. Low Bass notes can shake a whole room while high notes can't. Am I right about this? Light energy increase with freq while sound does the opposite? Please help me understand. Thank you.
From an educational perspective, fucking awesome. Keep up the great work!
For As chemistry 4:00
does he call the v in E = h*v for new or nu? 02:39. edit1: I get it, its a greek letter.
Really helpful
So if light is photons, how come radio is not? Because the only thing that's different is frequency, right?
According to a quick Google search (and two results from Quora), the photons are still there. www.quora.com/Are-other-electromagnetic-waves-like-radio-waves-made-of-photons (This is in case anyone else wants to know. I know this comment is five years old.)
Excellent
mind map... nice!
Oversimplification, sometimes
Can matter exist without light?
+XvAvX through discussions I've had it is possible for matter to exist without light. imagine the universe grows cold as it ages. light exstinguishes. perhaps all matter condenses into a super black hole. once the last atom attaches to the mass, it would cause an implosion and ignite a fusion reaction, producing light. it might not be possible for light to exist without a source (matter), but light seems as if it can in fact be in a non particulate wave form.
+XvAvX absolute zero is impossible, but it could
Aww you're killing me you've got to use a trombone for the slide analogy instead of a violin.
So cool
How does this explain anything about light and matter? It's an instrumentation history class with a total omission of how LIGHT and MATTER actually INTERACT.
"Light and matter." You literally just answered your own question, fool.
must be the visuals o.o
Very interesting video and i shared to my friends .
Also i suggest you see some interesting videos on SALEH THEORY-com about behaviors of photon.
The solution for scientists is for them to solve their major problems
by observing themselves being observed by their Selves in a Mirror.
This way they'd be able to see clearly how funny they look in ernest
since they desire to know about things but not so much their Selves.
cool
Damn
I want lawful Lambert Beer instead.
Nice work.
But, light and matter are both undefined things as is energy.
It's very safe to say that nothing makes sense. Thanks to our overlords.
🙏 Just wanted to wish you and your family a very Merry and Blessed Christmas Holiday and always. 😎 Lord-Jesus-Christ dot
At school bored.
stop it get some help
