In this lesson, you will learn what infrared radiation is, and how we can use it to visualize the heat signature of objects. We will discuss that infrared light is simply a part of the electromagnetic spectrum that we can't see with our eyes, because the photoreceptors in our eyes aren't receptive to the energy level of a photon in the infrared range. We will learn how William Herschel accidentally discovered infrared light by measuring the temperature of the different colors of sunlight after the light was split by a prism into the colors of the rainbow. Herschel found that the hottest part of the spectrum is actually outside the visible region, and we now call these infrared waves. We will also discuss blackbody radiation, and learn that all bodies at a given temperature emit radiation, including in the infrared.

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'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 UKposts. 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 UKposts 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.

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).

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?

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.

Colour - Visible Spectrum, Wavelengths, Hues | Britannica 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." Solar Spectrum: Solar Radiation and Irradiance | Ossila 4. "Hue, or color, is the main part of what people mean when they say “skin tone.” Most human skin is some variation of orange, either brighter or darker, more red or more yellow. Hues in the skin can be a result of genetics, or can be affected by things like sunlight, ambient light temperature, and blood flow." What is Skin Tone?

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.

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
@MathAndScience
@MathAndScience Рік тому
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.

Nice one - a difficult subject to "understand" and bring across - not only the E=hf part - but also the fact that red light is not that powerful/dangerous - but a red Laser can be pretty dangerous - so why? (Amplitude - amount of photons). I would however ask you to go back and check out Emily du Chatelet - who seems to have worked on the stuff you finish off with (a poker which is red hot but then is no longer visually hot but can still be felt as warm from a distance) - should she in reality be acknowledged with the "discovery" 60 years before? And if you also look at the fact that Williams sister Caroline had been working with him for 28 years by the time (arguably being the smarter of the 2??) Should she be totally forgotten because of sexism of the day? She published an astronomic catalogue 2 years later under her brothers name - just saying! I recon girls rock and history should be revisited and rewritten where it is questionable. Keep up the education.

Looks like yellow/green comes from the sun with the most abundance. So, why isn’t that color the hottest?

Just to point out what kind of garbage UKposts has become. Within 15 minutes of this clip I've had 4 ad interruptions with more time, had I not skipped them, dedicated only to ads, like nearly a hour worth of ads already.
