Great job. I'm 72 and love knowledge and learning new ideas. As a younger man I was a poor student but always curious. You have hit the sweet spot of teaching for struggling students with your patience, explanations and detail oriented presentations. Please continue your good work. I've a lot of catching up to do.
I love your comment, Dave, very much. By the way, 75 is just the middle of your age. I want people to live long and happy. Curiosity is one of the components of longevity. Live long and healthy, Dave )
I'm trying to learn here. I'm a construction worker who had a troubled past (difficult childhood & up bringing) so I never really paid attention in school. Now in my later years I've been trying to self-educate. I'm a slow reader, so I've learned to harness and take advantage of the wonderful power of the internet and RUclips. On multiple occasions throughout my childhood, myself and my parents were informed that I possessed an above average IQ despite my inability and unwillingness to participate class. I've always been interested in why things are the way that they are. Literally everything. Why are we here, how did the universe and Life Begin, how are we able to see, what is fire, space ,time, ETC, ETC, on and on....... Anyway thank you for sharing these videos. The videos that you share, as well as the videos of many other content providers on RUclips have helped me tremendously with educating myself and expanding my knowledge in my adult life. I was a bit confused when you brought up Planck's constant. Just a suggestion, when trying to reach out to the lay person and explain what Planck's constant is. Instead of referring to it as just a number perhaps you could refer to it as a baseline number, a point of reference in which to compare other measurements to. I figured it out but I was thrown off for a second.
@bigfish8280 Ain't Perpetual Andragogy Fun? 😊 You Are Not Alone in Your pursuit of Knowledge as a Life Long Learner. Nor, revelations of mental accuties, later in life. I'm here, trying to wrap my head around the concepts of light, waves, rays, and all those numbers, with scientific notations, and the how's and why's of affects/effects upon my Amateur Astrophotography. Never had the time for my hobby, working two or three jobs . . . You know the story, I'm sure. Professor Gibson, is the only Prof that ever told me, "...the wavelengths and frequency go opposite of each other" (or maybe, I slept through that class ) 😅 It's So Obvious, to me Now! 😊 Have a Good One 😊 💫🌟💫
Jason. You are the man. I bought the full course bundle a little over a year ago and have been working through the material since. I can't express enough how much I appreciate your approach to teaching/learning, as well as your efforts to cover such a broad scope of knowledge in such careful and thoughtful detail. I watched the back of my eyelids through most of school so what you do is greatly assisting my confidence for the future. I hope you are doing well, I hope life is good to you, and I hope you know you have great purpose.
I love the way you ended the video. As usual, you always leave something to inspire other for continuous study and further more to explore undiscovered things of the universe. Because I guess you know for sure that human kind just know very little about the universe. Dark matter, dark energy and may be anti matter are still hard to understand concept to majority audience. It is so motivational that you mentioned at the end. Thank you!
I appreciate how you step through the basics to build a comprehensive understanding that can make sense of different perspectives and enable more accurate predictions when the distinctions you detail are shifted. This brings to mind the origins of EM radiation and types of EM waves. For example sunlight begins with plasma reactions as impulse EM radiation which is not the same as the chemical or stimulated emissions in our atmosphere (sine wave EM radiation) the singular type of radiation you cover here. Past researchers have asserted that these waves have different propagation and impact on various materials (for example, without an atmosphere, stellar plasma impulses are invisible or transparent to our eyes without a transmuting atmospheric effect. This behavior was replicated by Paul Pantone with his GEET reactor that used a pressure induced Z-pinch plasma reaction in steel tubes that became transparent when the reaction became strong enough (freaked him out, fearing his engine using the plasma for fuel would exceed the physical limits of operation, he also did not fully understand the differences of plasma reactions vs. chemical reactions which could not transform the chemistry the way he measured his reactor operating. He had a cold fusion, plasma reactor designed using tricks to optimize fuel efficiency (crazy luck using CIV in magnetic fields with polarized chemicals. Similar to how stars form.) Detail how the wave shapes differ especially the magnetic fields and how they physical reactions differ. Tesla found EMPs can be totally unaffected by most matter, and extremely reactive with specific matter that resonated with very specific wavelengths (melting or exploding on contact) he also claimed the impulse transmissions were superconducting (how starlight can travel billions of light years).
Great point. The limits of human sensory systems should not negate the existence of of other realities that are out of our range of perception. Following this logic, modern satellites now use expanded spectrum mapping ,and convert those images to our limited human spectrum for analysis.
Thank you! You explain everything crystal clear. I love your new project 10 Minutes science. Because of your clear explanation I have a passion to understand more and go deeper. I truly appreciate your work!
You make math and physics fun to learn:-) Hope you will create a follow up video of the Electromagnetic Spectrum where you use the equation for calculating the UV-index or estimating the amount of sun power that can be harnessed in a solar panel as a practis sample.
Very interesting.. recently I published a book in Amazon Kindle on my Metaphysical Inquests into Nature: Mind and body as instruments.. as an outcome of that, now I have planned to start with Plasma.. your talks give me confidence that I would be able to do better progress..though I am a beginner on this subject.. one of my postulate is as human beings we have optimised our resources, faculties, senses, sensitivity..to maximize our survival.. now I understand our eyes and skins as what they do..reminded of boyhood lying on hot rock bed on a summer.. sensing heat and reaching dehydration..in a week my skin would go dark and would take three months inside office or cold place to regain some shades back..
We're done with that lesson... I'm studying in the Philippines.. but thanks.. anyway I have a question about increasing decreasing increase decrease.. can that be the topic of your next video please🥰
Im your fan from Germany Thank you for the great videos They all very rich information. Can you please do a video about the mechanism of the Aromachemicals in fragrance!
Hmmm, looking at your curve, why isn't the most heat gain located around yellow (more or less the peak of amount radiated)? If, as you seem to say, the energy of different wavelengths is swamped, in sunlight, by the quantity of photons?
So if I have understood correctly, that more heat is a result of a higher quantity of low frequency radiation, what is it that's causing the quantity of those photons? I know the simple answer based on what you've explained is "the sun," meaning the sun is what is determining the quantity, but what specifically about the sun causes the quantity of photons at a particular wavelength? Is that all heat really is, some sort of ratio of quantity of photons for a particular frequency? I have so many questions lol. Now Im curious if the sun sends less violet rays than red rays for example, how the heck does that work? What about the sun determines the number of photons per frequency? Would that ever change and suddenly more violet rays are sent and less red? Fascinating.
Great video. Just a question: referring to your graph (wavelength distribution of the sunlight), shouldn’t be the highest temperature somewhere in between violet and red as there is a maximum between 400 and 700 nm?
Thanks for the great video. According to the Black Body Curve graph 16:45, the green/yellow portion of the visible spectrum arrive at Earth in greater amounts than red. Since green/yellow are also higher frequency/energy than red, it seems that the highest temperature should be seen as either green or yellow. However, the image at :45 showed the cool portions of the house as green and yellow. Could you elaborate?
Isn’t red/infrared warmer because its frequency is more efficient at shaking the atoms? Like you can’t get a swing go high if you just keep on pushing and shoving it frequently - you need the right cadence there. Or microwave for heating food as another reference.
Correct me if I'm wrong, but I think infrared has an increased temperature because the infrared wavelength resonates better with the frequencies of the chemical bonds. I think that has more to do with the increase in temperature than the volume of photon packets.
Actually different frequencies of photons interact with matter in different ways. Infrared photons are resonantly matched with the vibration of various molecules or molecular groups. Since temperature is a measure of the average kinetic energy of a substance, the infrared photons are the ones that are increasing the vibrations and thus the kinetic energies of the molecules of the system. The higher energy photons with higher frequencies affect the orbitals of the individual atoms in the molecules rather than the kinetic energy of the molecules themselves. Higher energy UV, and X rays actually cause electrons to leave the atom forming + charged ions, thus the term ionizing radiation.
Why is infrared radiation associated with heat even though the EM spectrum beyond it (including visible light) is also heat and even hotter? Perhaps because it is the part of the spectrum where we FIRST FEEL heat, even if we can't see it. The sense of touch before the sense of sight.
Good morning sir, I am Nazeefi watching from Nigeria a Computer Science Student as well. I really find your lessons very interesting. Sir, please can you explain more about what differentiates between AM and FM in radio station and elaborate on mathematical methods as we do it more in computer? Thank you
Thank You Professor Gibson 💐 "Herschel's Calorific Rays" I incorporate, into this Celestial Sexegenarian's toolbox of Amateur Astrophotography File: "WhyInTheHellaTarnation Did my picture not come out right?' You Have Sir, a subscriber 😊
Your explanation of Planck's constant is a bit confusing. You say it's just a number. I'm trying to learn, I'm no expert. But wouldn't it be better referred to as a baseline number instead of just a number. A point of reference in which to compare other measurements to?
Wow... and I thought infrared had some special 'heat' property for all these years! I guess it's just about intensity. Explains why I have a blue laser (not even U.V.) that burns everything in sight (high power input?). Thank you as ever sir for freely sharing this section of your knowledge. 👍👍👍
For the same wattage, which colour DIODE laser is more effective at burning a black material? I would have thought higher wavelength? I guess it's far more complex; energy absorbsion/chemistry etc.? Dunno. Somebody please help! Thanks.
Nice 👍 Before watching... Infra refers to below or less. Red in reference to red in the visible light spectrum "ROY-G-BIV" So my guess is below red in the visible light spectrum 👍 ...or something close to that
since infrared can't be seen audibly 20hz to 20k hz is the theoretical human hearing range... so by analogy anything lower than 20hz or above 20k we can't hear either So that's what I was thinking
I'm no physicist and it's probably just a fluke but I did guess the reason for the temperature difference correctly as an issue of density. I guessed this due to something I suspect is similar and would like to know if it's correct: is it not the same issue as we find in a fluid flowing in a pipe where volume or cross-sectional area, velocity, and pressure are constants and the pressure drops when the velocity increases because the volume can't change? And so with the light, an increase in energy in the photon would increase velocity and therefore reduce density or pressure? And the slower photons, released in equal volume, volume, velocity, and density being constants such than one reduced means one of the others increased, and lower energy making a slower velocity and thus the density is increased? Is this right or not? Can anyone let me know?

I'm more than likely wrong but isn't the atom bomb sort of achieved in this same manner with splitting one atom that splits two atoms that splits four atoms and then eight into sixteen atoms and so on and so on??
Great knowledge. Great question, what don't we interact with, what don't we have senses for..... like dogs who smell things we can't smell at all........ do a lesson on things we can't sense
Am I the only one that is wondering why the infrared is hotter than yellow/visible red? According to your chart and theory, the temperature should be dropping dramatically after visible light
It’s a good question, and there are a lot of reasons, but I couldn’t cover all of them in a single video. Remember that the sky is blue, that will probably be a separate video one day, but basically the sky is scattering different wavelengths of light, so what we see on the ground is after the atmosphere has scattered the different wavelength of phototons. Also, the atmosphere absorbs different frequencies as well, so what we’re seeing on the ground is after the atmosphere has absorb different wavelengths. Then there’s also what I mentioned in the video, which is the sun does not radiate all wavelengths of photons equally. So in the video when I was talking about measuring the temperature of infrared and the experiments, it was mostly to motivate and show you how it was discovered. What we measure on the ground as far as the temperature is after all of these are facts are taken into account and that’s why it can seem a little backwards.
So actually i think that we humans dont mainly focus on the features of the moon but i think that the way the moon pulls water with force has a relationship with us humans sleeping
All electricians that does TV Antennas should watch this video, because they know absolutely nothing, but yet in Australia they do TV Antennas, because RF Technicians doesn't exist in Australia
I know that at some point more mathematics will be introduced, but he has a beautiful way of slowly building innate understanding and greasing the skids for easier consumption of the numbers and formulas.
So basically when we put sufficient heat in a metal we are effectively shifting his "emitted photons" left - straight into the visible spectrum. Because the higher the energy the higher the wavelength frequency.
4:30 here, you made the common mistake of assuming that we see every wavelength in the "visible spectrum", even after you just concluded we can in fact see only blue, red, and/or green wavelengths. those high tech devices will be able to detect "orange" light when our puny eyes see black, wrongly assuming the object isn't radiating color until further inspection.
9:08 yes, the falsely named "visible spectrum" is a tiny sliver of the full breadth of light frequencies, and yet we still only see a tiny sliver of that spectrum, too, having receptors activated by only RGB. we don't know what 420 nanometer packets look like.
So a metal cup filled with dry ice and both the dry ice and the cup are far below zero, the infrared camera would not be able to "see" the cup of dry ice as long as the temps of both were below zero. Yes?
I think what confuses people the most is they think of EMR as light instead of emf and having certain emf visible to humans. Even though technically they are the same because they are packets of oscillation. Where it gets confusing is people understand light needs a source but an antenna radiating radio waves isn’t visible. Different emf have different sources. Imagine seeing visible light propagating off an antenna 😂 I would like to see 700Thz through antenna. Not sure if that would even be considered possible.

I am Nazeefi watching from Nigeria a Computer Science Student as well. I really find your lessons very interesting.
Sir, please can you explain more about what differentiates between AM and FM in radio station and elaborate on mathematical methods as we do it more in computer?
Thank you
Thank You Professor Gibson 💐

You Have Sir, a subscriber 😊
Fascinating, but it gives me the dirigible blues. Do you have a watts description - calculation of loads tutorial?
thank you for teaching us simple folks
Sir Make one video in reference of black hole😊
You are good teacher.👻💖
Your explanation of Planck's constant is a bit confusing. You say it's just a number.
I'm trying to learn, I'm no expert. But wouldn't it be better referred to as a baseline number instead of just a number. A point of reference in which to compare other measurements to?
21:50 messed up the explanation for the human perception of infrared radiation as heat. it's because our bodies are infrared sensors.
Wow... and I thought infrared had some special 'heat' property for all these years! I guess it's just about intensity. Explains why I have a blue laser (not even U.V.) that burns everything in sight (high power input?). Thank you as ever sir for freely sharing this section of your knowledge. 👍👍👍
For the same wattage, which colour DIODE laser is more effective at burning a black material? I would have thought higher wavelength? I guess it's far more complex; energy absorbsion/chemistry etc.? Dunno. Somebody please help! Thanks.
SO CAN THIS INFRARED CONCEPT BE USED IN RADARS AND NIGHT VISORS?.
Outstanding
Nice 👍
Before watching... Infra refers to below or less. Red in reference to red in the visible light spectrum
"ROY-G-BIV"
So my guess is below red in the visible light spectrum 👍
...or something close to that
Nice! Interesting!
since infrared can't be seen
audibly 20hz to 20k hz is the theoretical human hearing range... so by analogy anything lower than 20hz or above 20k we can't hear either
So that's what I was thinking
So nice thanks sir
How did he found the location of infrared radiation so that he measured it's temperature?
I'm no physicist and it's probably just a fluke but I did guess the reason for the temperature difference correctly as an issue of density. I guessed this due to something I suspect is similar and would like to know if it's correct: is it not the same issue as we find in a fluid flowing in a pipe where volume or cross-sectional area, velocity, and pressure are constants and the pressure drops when the velocity increases because the volume can't change? And so with the light, an increase in energy in the photon would increase velocity and therefore reduce density or pressure? And the slower photons, released in equal volume, volume, velocity, and density being constants such than one reduced means one of the others increased, and lower energy making a slower velocity and thus the density is increased? Is this right or not? Can anyone let me know?
Can you shed some light on the Ultra violet spectrum?
Thank you very much ♥️
You're welcome 😊

2. "The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies...This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low-frequency (long-wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end." Electromagnetic spectrum - Wikipedia
3. "The solar spectrum is the range of electromagnetic radiation emitted by the sun, extending from the ultraviolet to the infrared region. It is composed of photons with various wavelengths, which define the spectrum's shape and intensity. It can be defined in terms of solar radiation or solar irradiance."

I'm more than likely wrong but isn't the atom bomb sort of achieved in this same manner with splitting one atom that splits two atoms that splits four atoms and then eight into sixteen atoms and so on and so on??
Thank you
Oh super knowledge
Great knowledge. Great question, what don't we interact with, what don't we have senses for..... like dogs who smell things we can't smell at all........ do a lesson on things we can't sense
is temperature is EM waves mr jason ?
Am I the only one that is wondering why the infrared is hotter than yellow/visible red? According to your chart and theory, the temperature should be dropping dramatically after visible light
It’s a good question, and there are a lot of reasons, but I couldn’t cover all of them in a single video. Remember that the sky is blue, that will probably be a separate video one day, but basically the sky is scattering different wavelengths of light, so what we see on the ground is after the atmosphere has scattered the different wavelength of phototons. Also, the atmosphere absorbs different frequencies as well, so what we’re seeing on the ground is after the atmosphere has absorb different wavelengths. Then there’s also what I mentioned in the video, which is the sun does not radiate all wavelengths of photons equally. So in the video when I was talking about measuring the temperature of infrared and the experiments, it was mostly to motivate and show you how it was discovered. What we measure on the ground as far as the temperature is after all of these are facts are taken into account and that’s why it can seem a little backwards.
So actually i think that we humans dont mainly focus on the features of the moon but i think that the way the moon pulls water with force has a relationship with us humans sleeping
All electricians that does TV Antennas should watch this video, because they know absolutely nothing, but yet in Australia they do TV Antennas, because RF Technicians doesn't exist in Australia
I love this guy can learn from him,
I know that at some point more mathematics will be introduced, but he has a beautiful way of slowly building innate understanding and greasing the skids for easier consumption of the numbers and formulas.
So basically when we put sufficient heat in a metal
we are effectively shifting his "emitted photons" left - straight into the visible spectrum.
Because the higher the energy the higher the wavelength frequency.
Great. Thanks
4:30 here, you made the common mistake of assuming that we see every wavelength in the "visible spectrum", even after you just concluded we can in fact see only blue, red, and/or green wavelengths. those high tech devices will be able to detect "orange" light when our puny eyes see black, wrongly assuming the object isn't radiating color until further inspection.
9:08 yes, the falsely named "visible spectrum" is a tiny sliver of the full breadth of light frequencies, and yet we still only see a tiny sliver of that spectrum, too, having receptors activated by only RGB. we don't know what 420 nanometer packets look like.
how ironic to speak so blindly about the phenomenon of sight.
So a metal cup filled with dry ice and both the dry ice and the cup are far below zero, the infrared camera would not be able to "see" the cup of dry ice as long as the temps of both were below zero. Yes?
the like number 1000 😍
thanks
That 1 girl that was red had the vaccine ;)
Cause she got banged hard , oopos sleeping when writing this shit.
permission to use ur words and idea,
I agree with you for the most part but the idea or existence of dark energy and dark matter I would question
It appears that infrared 'exists' throughout the spectrum. Evidenced by the 80 to 86 degree difference.
Well, infrared is just a label given to a range of wavelengths in the spectrum.
@@MathAndScience a bit complicated for sure..liked your laser video, bbetter than my 11990 intro to lasers class in a ABQ. N.M.
we are all glowing
This is the way the alien in the movie, "Predator" was able to track his prey!
Some snakes also do it this way.
Would revelations be some kind of huge big waves? A nice fantasy, I think, after all, magic is the mother of mathematics.
But! Violet is violet because it is blue mixed with red. In the color spectrum, red turns into violet. How can these be polar to each other?
There is RGB and CMYK they are not the same
I think what confuses people the most is they think of EMR as light instead of emf and having certain emf visible to humans. Even though technically they are the same because they are packets of oscillation.
Where it gets confusing is people understand light needs a source but an antenna radiating radio waves isn’t visible. Different emf have different sources. Imagine seeing visible light propagating off an antenna 😂 I would like to see 700Thz through antenna. Not sure if that would even be considered possible.
👍👍👍👍👍👍👍👍👍👍👍👍
Excellent keep it up
Thanks so much.

Why not say how it is produced, no effing professor says how infrared is made, is it from electrons falling down to lower orbits or just a property of atoms?
It would have been better to say or show that solar radiation os approx 50% Infrared...
Please why is the Sun not sending that uv, gamma to the earth?
Can cats detect IR radiation?
as per color why red fire is not hotter than blue fire 🔥.blue fire is considered hotter as compared to 🔵 blue.
