Minor corrections: There is no such thing as "high voltage current," it's better to say something to the tune of "The application of a high voltage results in sudden dielectric breakdown of the air resulting in a strong impulse response or electrical snap." Maximum power transfer theorem states Zl = **Zg, or the *CONJUGATE* of the impedance, not equal. this allows the maximum use of electrical "whiplash" at the resonant frequency.

@@ahmdabdallah2132 Too bad God does not actually exist except for as a concept in the human mind. Unless you have any actual evidence of God's actual existence. For those who claim God exists, consider the following: a. An actual eternally existent absolute somethingness truly existing. b. An actual eternally existent absolute somethingness that has consciousness, memories and thoughts truly existing. People who claim God actually and eternally exists basically are claiming that 'b' above is correct but yet simultaneously seem to be saying that 'a' is impossible to occur. 'a' above can exist without 'b' existing but 'b' cannot exist unless 'a' exists. I am one step away from proving God's existence, but am unable to find any actual evidence to do so. And nobody I've talked to seems to have any actual evidence of God's actual existence either. Hence, at this time in the analysis, God does not actually exist except for as a concept created by humans for humans. Humans have personified Nature and called that personification "God". * People who make super natural claims, the onus is upon them to prove their claims. They are certainly free to believe whatever they want to believe, and others are certainly free to believe whatever they want to believe. Via a lengthy analysis I currently believe that people who believe in God are delusional and are believing in fairy tales as if those fairy tales were really true. And if they couldn't prove otherwise, then they couldn't prove otherwise. They have been brainwashed well. KUDOS to those who brainwashed them. * So again, I ask where is any actual evidence, any actual evidence at all, that God actually factually exists?

Just a few notes :) Hertz's experiment: It wasn't the spark that transmitted the wave (Edit: the spark itself will / is able to emit an EM wave though). The spark merely triggers the dipole oscillation. He used a massive DC voltage surge released into an oscillator (or without it) and then to a tuned dipole arrangement with a spark gap. The spark fluctuates, behaving also kind of like AC, that's why it worked even without the oscillator. The dipole then produces a dying wave, not a continuous wave. The wave is emitted by the whole dipole, not by the spark in the middle of it. Herz created the first dipole arrangement by pulling a capacitor electrodes far apart (the balls). The emitted wave was received on a loop that really was another LC resonator (L was represented by the loop or square of certain diameter and C was represented by the gap). 6:50 if the impedance of the power source/cables doesn't match the dipole input impedance, the power is reflected right on the transition point between them. This looks like it is reflected on the dipole itself. I really liked the portion of the video, where you explain how the EM field leaves the conductor.

[@icommentio]

"the spark fluctuates, behaving also kind of like AC, that's why it worked even without the oscillator." it does not fluctuate . it just lives for some time. say 100 microseconds. and the natural frequency was 100 MHz. so the oscillations are between the spheres (a capacitor) connected by a piece of wire (an inductor)

[@TheYeeshkul]

@@icommentio The current between the gap electrodes is not clean DC, it is "hairy". That is what is needed to emit a wave. I guess this is a complex problem where the spark gap, which is able to emit a wave itself, feeds an oscillator that will make the wave go longer and be cleaner in shape.

[@scottjacobsen4961]

I design mobile cellular antennas as part of my job. I thought the video was a great depiction, showing the propagating mode(s) as a kink, but I should clarify that antenna designers for cell phones don’t use halfwave dipoles. Rather, we use a random geometry of antenna traces to transfer energy from the board to near fields and hope that in the mess of fields surrounding the cellphone, some form of propagating modes also arise. A little shared secret among antenna engineers is that we don’t have a clue how our antenna actually work as it’s impossible to decompose fields into their constituent components using full wave simulators. We can only look at the aggregate fields. With a dipole, it’s easy to analyze and the modes pop out of the math.

Nice video. Note that the electromagnetic wave does not move in a sinusoidal 2D wave, but in a circular 3D motion that translates into 2D waves when we detect them because we are only measuring on point in space.

This level of explanation isn't easy to find. I've wondered about this for years and finally decided to find a real explanation.

I can suggest a few things. First, take notes. You'll have a better chance of understanding things if you remember more of it, and simply writing something down will help with that. Look up any terms you don't understand. Third, watching other videos or reading other texts about the same thing. And fourth, be patient and persistent. You've got your whole life to figure this stuff out, take your time with it and have fun. But if you keep at it, you'll find yourself learning things you never thought possible. Another thing that helps with general knowledge is to make a point of learning just one new thing a day. Best of luck to you. And don't forget to enjoy the journey of learning. Cheers.

There is a mistake in this video: magnetic loop antennas exist, and they have extensive use between amateur radio operators (magnetic loop antennas are a single turn coil, fed with an alternate signal, just as the dipole antenna). In this video, they present loops antenas as they were useless, which is not true at all.

Electrons in the dipole antenna doesn't actually move along the wire as shown in the diagram since electrons move very slowly (few cm/s). What's really happening in the conductor is much more complicated as it's a superposition of all the electrical field produced by the accelerating electrons. It's not something that can be appreciated intuitively, however this animation provides a good enough explanation.

[@mibrahim4245]

I have couple of questions if you don't mind .. The first: how do kinks move at the speed of light, while their cause "the charge acceleration" moves in a speed much less than the lightspeed ? how do they move faster than the thing that created them ....

[@rotate85]

@@mibrahim4245 Hi, sorry for the late reply but I only saw this now. Kink isn't a thing on it's own. It's just an imaginary line that connects the point in space that have the same electrical field strength. Kink isn't something that moves, although the animation shows this. This is because the electrical field is mediated to all the space around by a virtual photon which does travel all the speed of light. What it trying to demonstrate is that when the charged particle accelerates, the electrical field is updated to the space at the speed of light.

[@mibrahim4245]

@@rotate85 Thank you for the reply .. I'm very interested about this particular detail and I'd like to "digest it" so plz bear with me .. now the charge has accelerated.. and the information about the electric field strength updates with lightspeed.. so why if it is so fast.. why would it have a problem (creates kinks) when the charge accelerates (but not when its stationary or with constant speed).. whats the difference if in all cases the information would update very quickly.. and he said "the space near the charge would update normally, but the space 'away' from it would have kinks .. so again, why does it happen if this update is so fast ... the second question is about propagation.. I saw in other books that it happens because the E field creates B field, and that B field creates E field .. and so on .. so is that the why ? this detaching energy as in this animation was not very convincing for me ...

Everything is a wave, a wave is formed in its own material, therefore if electricity is radiated as a wave, then that wave must be formed in electricity that is around us.

[@jeffclark2675]

I have a BSEE degree which included multiple high level calculus-based classes in electromagnetic fields. this video explained the concepts better than all of those classed combined! Bravo to the developers of this video! A few questions below. At 2:19 the kink is said to move or radiate outwards at the speed of light, seemingly implying that this was the EM wave. But then the kink is shown as occurring at 3:37. This is before the two charges (and the fields between them) later meet and the EM wave is transmitted . Is this the difference between a photon and a wave (a collection of photons)? Do both actually occur? In other words, at 2:19 when the kink is formed, does this produce a photon(s) reconciling the kink from a single charge later followed by the transmission of the whole wave occurring when multiple photons collide from the multiple charges meeting? What is the blob of objects at 1:39? I am assuming it is the "charge" mentioned just previously? If so, is the blue dot that emits from it at the speed of light (referred to as "the information") a photon? Where does the photon get the energy to emit outward at the speed of light? Is it from the energy that must have been present to cause the acceleration of the charge? Or does it not need energy to accelerate because it is massless? If it is massless, why is it depicted as having a negative charge at 1:46? Why does "the field near the charge" need to "communicate" the "information" to the "field further away" at all? this implies that the fields have some intelligence and use the "information" to adjust their fields to reconcile the delta. Would it be advisable to omit this in favor of the really insightful bit about the delta being reconciled to prevent a discontinuation (correct the disturbance) between the two fields? (a disturbance in the time/space continuum). Can we also think of this as an energy problem? Could we say (from Newton's second law) that the change in speed, or acceleration, requires a force, which increases the energy state of the moving charge? Could we further way that the photon is emitted to release energy and establish equilibrium (from a conservation of energy perspective)? If the entire universe consisted of a single positively charge particle, would that positive charge have an electric field?

I think they were trying to illustrate impedence by using a combination of real-world loads in that example at 6:08 .

What is misconstrued as a particle is most likely a node or singularity. We cannot hope to advance understanding if we hold to this concept that everything is created from smaller & smaller particles, i.e. quanta. Example, the reason that electromagnetic waves and light both travel at the same speed is because light is an electromagnetic wave. There is no light particle. Light slows down when passing thru a prism because it’s an electromagnetic wave, not a stream of particles. There are no dualities in nature. Wave-particle duality concept is a misdirection. Perhaps deliberate.

About halfway into I started dreaming about neurolink , would be my only chance of understanding it.

[@ambientsoda106]

its amazing Maxwell could learn this in his time!

[@zeorxofline]

I am still amazed how those guys invented these fundamentals of electricity about 200 yrs ago with no computer or any advance technology and did all the math, and yet we still struggling today in 21st century to understand these inventions !

[@davidlinney2765]

EM waves magnetic and electric components should have a 90 degree phase difference. The change one causes the other. They can't both have maximum and zero values at the same time.

[@stargazer7644]

That is incorrect. The electric and magnetic fields are in phase in a traveling wave. They are perpendicular to each other spatially, but in phase temporally. They both peak at the same time, but at right angles.

I wish I had this amazing videos in the 90's to better understand these concepts, but I hadn't so it was much difficult to abstract them on just pictures or maths

Step 1 from hopper connected to collection plate, release one ball every 1.3 seconds onto a slope to roll to magnetic lift zone staircase. Step 2 the metal balls roll into stationery magnetic fields from fixed position magnet a piece of wood or solid plexiglass with triangle shape to force balls into a direction onto stairs repeatedly increasing potential energy. Step 3 drop metal balls as kinetic energy onto river wheel generator’s right side only turning it to make direct current energy for large dc solar batteries with an alternating current transformer with outlets of the appropriate type. Step 4 after the metal balls turn river wheel generator let them fall onto a high collection plate connected to a hopper, the metal balls never stop producing potential energy from magnets potential elastic energy to be converted to kinetic energy to make an endless river of metal balls for a river wheel generator

[@every1665]

I hadn't thought about the high velocity of the electric charge causing the emitted waves to be distorted. Thanks.

[@DrDeuteron]

acceleration, not velocity.

[@kokomanation]

This animation with the moving charge reminded me of the Doppler effect

[@briankamras2913]

This video was AMAZING! I understand how EM waves are formed! They're just disturbances in the EM field and they have a speed of light because they are the carriers of information!

[@DrLumpy]

6:20 I'm a little bothered by the animation of the "circuit". Not sure what kind of circuit you're describing. A light bulb, electric motor, and a power supply in series with an alternator output?

Do you have ADHD? Not in any way trying to offend or anything, I know people who have ADHD and catch migraines trying to do some math problems. It's like sometimes intense concentration causes headaches. Do you know what I mean?

[@88foldpath]

@@derekprice2873 I at least have ADD, not sure about ADHD though. I can focus on studying usually quite well if the environment and my mood is right and I've taken the time to thoroughly understand a subject. If it's beyond my level of understanding however and my brain can't make sense of it and connect the dots then I get mental fatigue and want to sleep lol

[@88foldpath]

@@derekprice2873 like in this video I could make sense of what he was explaining to a point but then he kept talking, maybe moving too fast for my comprehension, and then my brain fell off. If something doesn't put me to sleep then at least I've learnt something hahahaha

I wanted to make an antenna for my 2.4 GHz transmitter and wavelength of 2.4 GHz frequency is 12.5 cm so half of it is 6.25 cm which would be good for transmission and receiving according to the video. This video answered my questions which i did not find after a lot of searching.

Please can you help me to get a grip with this ,I am being targeted by gangstalkers,and I have to try to get evidence to support a investigation by police, I am not off my rocker and 50yrs old,they are trying to force my partner to sign his assets to them and they are seeming to be getting the away with it,they are slowly killing us ,this is a desperate last attempt to get it sorted out and we can get our lives back, please can you advise me

That's why Quantum Field Theory is very interesting . Everything is a kind of FIELD. Its already there. 1. Electromagnetic filed 2.Electron Filed 3.Quarks field. 4. Gravitational filed. Actually there is no particles , but Field.

Hertz said the radio waves he discovered were proof that Maxwell was correct about EM waves, but otherwise they were unimportant. Maxwell, on the other hand, had laid down the laws that govern these waves, preempting QED with half of his EMT equations. Even Einstein said Maxwell was the giant on who's shoulders he stood. I don't think he mentioned Hertz.

Outstanding video on Radiation.

Oww maam your lesson is great and more understandable due 2 the awesome animation

[@GAND-OZZ]

1:40 exactly what atom is this? I’ve been trying to find it for a long time but I can never find it. I see some tritium and deuterium which indicates it’s a little radioactive (hence the name electromagnetic radiation). It might be tritium and deuterium mixed together but it would immediately become helium and a neutron so please tell my what it is.

[@TheBozn]

Looks like it could be beryllium-10

If I would have seen this when I was in college I would have gotten my electrical engineeringdegree in college. I try to learn this concept for my electrical engineering teacher but he never really had enough time to explain instead commented on the fact that but didn't get it I wasn't going to get it

[@TonyFarley-gi2cv]

Around second 44 I got this concept belief that we can use that design and print the dollar bill and make it a hell of a lot harder to hack it or restructure it's development through printing meaning you can design different conspiracy wavelengths are pattern structures that can catch recognizations
