Mr. Professor, thanks to this video I am able to calculate how many chromophoric centers in a sun cream I need, to dissipate sun energy in a period of time. Unbelievable.
Hi, dear Professor I appreciate your amazing lectures, including this one. However, if you don't mind, let me guess there's a mistake in counting of photons per volume. To count them per cubic metre for example, it should be multiplication ✖️ not division ➗ process. Would you agree?
@@MichelvanBiezen I did explain, dear Professor. The last part about how many photons in the volume. It should be the number of photons in the squared metre surface ✖️ not ➗ the volume itself
@@LuisAldamiz Yes 44.4 micrometer is for the visible spectrum. Does that make photon size varies by wavelength, frequency, time? Does that make physical dimensions are measured by joule? Does that mean joule is a unit of physical dimension? Am I lost?
To be more precise: taken as a wave it tends to be relatively big (depending on frequency: the more energetic, the smaller it is)... but physicists often insist in there being true "point particles" in that wave, and such "point particles" are infinitely small by definition (zero size). This is of course part of the endless debate about the nature of quanta.
Why do you calculate for a CUBIC meter instead of a SQUARE meter?? Are you implying that a square meter of photons will travel one meter in one second?
We are calculating the volume density (number of photons per unit volume) and then we can calculate the number of photons in a beam of light with a cross sectional area of 1 m^2 and a length of 3 x 10^8 m which is the same as the number of photons striking an area of 1 m^2 in one second.
Huge thanks for your help of understanding plus loving physics again. l've watched several videos of you and never miss a point. lf you saw my lecturer's note you would understand me why l started to think about suicide because l'm a stupid student who can never understand basic perpectives of physics. lf my notes were in English l would really want you to see what we've been taught. Again thanks for your effort. l really appreciate that.
You need to keep re-emphasizing the fact that that is 3.4210^21 photons in that 3x10^8 m^3 volume of space passing through EACH SECOND. I know you said it, but you should write it: don't write 3.4210^21 photons but write 3.4210^21 photons/second.
It doesn't matter because you can conceptually freeze that volume. He actually calculated how many photons are (approx.) at any given instant in a cubic volume of sunlight: every instant some photons leave that space and others arrive, so time is irrelevant.
Somehow as many molecules of water turn into a river. Probably not identical but a good enough analogy. Not identical because atoms and molecules have a (very roughly) specific size, they begin to resemble "tiny balls", "objects" we can more or less understand intuitively, while photons lacking mass, etc. are rather in the crazy wave side of raw physics.
It seems the most obvious & logical explanation for a #particle acting like an #AxialWave when moving thru space is that it's orbiting something (a dark matter particle perhaps) or visa versa. It's not unlike Earth being pulled into a wobble by the moon, or a distant star's wobble evidencing planet orbits making our trajectory as we fly thru space have an axial wave (packet) as well. And since we think we know undetectable dark matter exists but don't yet know where it's distributed, this seems the most logical possibility. What do you think? This could explain the double slit experiment results, including with a detector with some interaction between the dark matter and the detector.
I STILL do not understand te connection between or know the formula that connects POWER of a light source to the ENERGY E = hv where h = Planck's constant.
This video would have made much more sense to me if you had calculated the FLUX of photons: the number of photons of sunlight passing through a square meter per second.
That is a wireless transmitter for the microphone. We now use a wired connection instead because we were getting interference from the airport transmissions.
Light is perturbations of the Aether field. Compression of the Aether field, until it bounces off the coaxial circuit of the Inertial plane. FLASH so called photons. Rarefaction of the Aether field. Repeat! "The smaller the spacial footprint, the higher the capacitance", = The Inertial plane/Counterspace. Light does not have a speed. Light has a rate of induction. Light needs both transverse waves, Dielectric energy and Dielectric voidence field/Magnetism. Lights rate of induction is the rate of creation of Magnetism. Because both transverse waves are needed to create Tesla Nodes, that EM waves travel on/in.
Professor, I continue to stumble upon more and more of your lectures that are answering so many of my questions. I really appreciate your videos!
Glad you stumbled onto our videos. There are 9500 videos on this channel. Enjoy! 🙂

Hi, dear Professor
I appreciate your amazing lectures, including this one. However, if you don't mind, let me guess there's a mistake in counting of photons per volume. To count them per cubic metre for example, it should be multiplication ✖️ not division ➗ process.
Would you agree?
We do make mistakes, (and like it when viewers point them out), but in this case which specific calculation do you think is not correct?
@@MichelvanBiezen I did explain, dear Professor. The last part about how many photons in the volume. It should be the number of photons in the squared metre surface ✖️ not ➗ the volume itself
You can have the number of photons ARRIVING at an area of 1 m^2, but you can also have the number of photons CONTAINED IN a volume.
You cannot have a number of photons IN a square meter of surface since an area does not have volume
You cannot have photons IN a square meter of surface. A surface does not have volume
Fantastic! Thanks for this.
Would that makes width of one photon 44.4 micrometer?
OK, now ask the same question within a visible spectrum?
This is in (mostly) the visible spectrum: he's talking of sunlight after all.
@@LuisAldamiz Yes 44.4 micrometer is for the visible spectrum.
Does that make photon size varies by wavelength, frequency, time?
Does that make physical dimensions are measured by joule?
Does that mean joule is a unit of physical dimension?
Am I lost?
Most interesting curiosity. TY.
Does that mean that a photon is trillions of times bigger than a proton, or it is just a matter of density?
That depends on the wavelength. But typically a photon is much bigger than a proton.
To be more precise: taken as a wave it tends to be relatively big (depending on frequency: the more energetic, the smaller it is)... but physicists often insist in there being true "point particles" in that wave, and such "point particles" are infinitely small by definition (zero size).

Space is trhree-dimensional.

We are glad that we were able to help. Physics can be very interesting if we learn it one step at a time. Enjoy.....
well made
Right on !
Sir thank you.....

How do discrete chunks of energy turn into a beam, which implies continuity.

I think instead of complaining, you should chunk down your knowledge in a paragraph and make it worthy to be pinned for future readers.
What type of technology are you wearing on the back of your belt?
That is a wireless transmitter for the microphone. We now use a wired connection instead because we were getting interference from the airport transmissions.
