Very stimulating to see the demos at a very human level rather than as diagrams in a book.

Loved watching the use of those grand old devices - great video thanks for uploading.

These physics videos are epic! I love the simplicity and the classic demonstration tools.

Beautiful demonstration of Electromagnetic Waves!

This is rather more amazing some one making you visualize the theories. I'm unable to put my remarks into words for such great explanation.

Great and fun demonstration ! Well done !

Nice demonstration... The use of the various devices clearly demonstrates the concepts and make it easy to internalize the theory.

This is fantastic. Every time you try to ask a ham radio forum about something like many useful concepts in this, your question is over their heads so high they think your question doesn't make sense and you must be doing or thinking something incorrectly. Then you'll get an educated one (the minority of outspoken individuals) but he's likely to do a a whirling dervish dance around the answer trying to make it intangible or illusive like a doughnut hole. By the time he's done beating around the bush, he's forgotten what point his anticlimactic crescendo was ever supposed to amount to. I get answers faster watching entire lectures like this one!

I'm just finding this great presentation now. I've been missing out.

I really enjoy learning, thanks for sharing knowledge Cornell University.

Thank you for the excellent demonstration....

this was excellent, i enjoyed it immensely. It would be great if cornell could do a more current version of this

Thank you so much for this great explanation of EM waves.

My uni profs comes with a laptop and read all the bullshit inside. This is just so cool with demo, and it makes understanding much easier

Fantastic lectures!!

What a beautiful way of explaining the concept . Heads off to you. And yes what happened with that electromagnetic wave you carried with yourself .

Very cool, I love the Early Days look of the junk involved. Great, really gets the mind open and working.

Best demo on You Tube about these phenomenon.

this was so great, really helped me to understand

Dude. Have you got your ham radio license yet?

It is the same as like the coupling between the antennas. When the conductors (transmiter & receiver) are parallel you have maximum absorbion.

Cool Cornell University video from 1981 demonstrating how radio works. Perfect foundation information! #hamradio

Nice demo.

Outstanding demonstration. Much missed in today's teaching methods I feel.

Thank you very much!

So great

this video is great!

where can i find more of these videos link plz someone?

Really amazing! Hats off to u Prof :)

It's fantastic to realize how diference is the education between first world and third world.. in my case never saw all this, 1981 now 2012 it's fantastic... Soy de Ecuador

That makes perfect sense to me. Thanks! "Could all direction be curved multiplying+/-dividing 3-D spherical waves inbetween an infinite number of vorticies? And there is no space, or rather matter is just space when and where it is very intense in violent motion simulating rest and balance now through violent motion. These opposing vorticies spiralling outward seem to combine together and we have the Fibonacci sequence in objects of broken symmetry that can be seen almost everywhere in nature."

that has actually been really good for people that study in countries that don't invest in props, such as mine ( i live in Dominican Republic), if it wasn't for power point we wouldn't be able to see things like this in some of my classes.

What kind of wave in the vacuum, how explaine TEM, phase ondulation of stationnary scalar wave space/time ... gabriel LAFRENIERE tell more about scalar field ...

Great video! Great Lecture!

Nice example of Standing waves with the red light showing the anti nodes.

Very nice. I have not thought or heard about galvinometers in a long time. Thank You

3 people not only do not understand physics but lack the desire to learn more as well as the appreciation for physics and the beauty of the universe.

The whole time he was handling all those tubes and (what appear to be) antique devices I was worried he was going to drop/break something. The ending of the first part was classic!

Yes I believe Q.A.T is correct. Matter is violent motion simulating rest and balance now through violent motion. The locational spherical inward absorption and outward emission of EM-Waves must be forming all forces of nature, antimatter matter annihilation forming + and - electric charge and EM-fields and the forward passage of time. The more violent the motion the greater the illusion of rest energy or mass the greater the absorption and emission rate the slower time runs within that ref-frame

very beautiful and attractive way of explaintion

I use a 5.8 Ghz transmitter and receiver! I fabricate new and more efficient antennas! Do you have any advice of what procedure of how to measure that output and specially the gain of different antennas? thanks in advance!

Can someone explain to me why the E-field can pass through the wire grid that's perpendicular to the E-field polarization? Thanks!

3:01 There's a leyden jar, spark gap and voltage source, it's said the spark gap breaks down and you get ac voltage. How is the voltage alternating directions?

@TheSundaysLive

5 жыл бұрын

The leyden jar and the spark gap create a pulsing current in the coil this gives a pulsing magnetic flux over the coil. When the flux is decreasing a potential difference over the coil is created which is opposite when the flux is increasing. This is called inductance and is responsible for the ac component.

gr8 vid thx !

很棒的示範教學，我從沒看過這樣認真教學，謝謝你。

what happens if you have a magnet core coil and you run electricity through the coil? Does it super-amplify the EMF field or shoot the magnet out of the coil like a bullet?

Hi sir need the complete video lecture on the Electrical Physics, I would like to know at what frequency will a human being get electric shock and in an Induction motor do we get electric shoch if we touch the rotor. Please provide a lecture series on the tesla coil, antenna fundamentals and design of antenna and Electrical Machines

Briliant ! Really enjoyed the humor. Where were you when I was at school. Too many theory based teachers out there, these demonstrations really helped me, thank you soooo much...great work !!

Espero tener la suerte de emcontrar un profesor como éste, que explique así, demostrando cada fenómeno con experimentos. Qué apasionante. ¡Muchas Gracias por compartir!

hello, i have a Q if you can answer.. can we destroy or absorb the electromagnetic wave 10µ. or may be can we change its frequency or wavelength after it is transmitted on the way ??? please answer me...........

Thank u

@iloveflyingac We can absorb the electromegnatic wave & change its shape but energy cannot be destroyed. EM wave is also form of energy. We can change its frequency by several ways. One femous natural phenomenon of change in frequency is "Doppler's Effect".

So Cool

How to the magnetic field and electric field get in phase when they come off the antenna 90 degrees out of phase?

@@rickwest2818 No, but you can develop the mental images by reducing the equation to what is happening in each point. How does a changing magnetic field cause an electric field? How does a changing electric field cause a magnetic field? When are they both in equilibrium? You can do this graphically if it helps or you can evaluate it mathematically. Having said that, it takes a good amount of time to develop an intuition and I have to say that mine was never very good for the free em fields.

Awesome i like it...

Motion within an infinite number of ref-frames, based on just one equation (E=ˠ M˳C² )∞ the Lorentz contraction of space and time is between the energy and mass. The greater the energy the greater the contraction of space and the slower time will run. Mass will increase relative to this and each ref-frame can be seen as a vortex in space formed by the rate that time flows. The brackets represent the boundary condition of the ref-frame formed by the energy within infinity

some sweet info here

thanks a lot

25:20 = silly and lol. I did quite a few of these experiments in my Conceptuals Physics class. Thanks.

Awesome

'Space is a division of solidity into tenuity. Also a multiplication oscillating volume at expense of gravitational potential. Now matter in violent motion is simulating rest and balance through violent motion. In the future Heisenberg's limit will be required time cycle for quanta to exist. The interval of the becoming moment reaching its threshold when C is cancelled out by its anti+C, collasping and reforming+/-eXploding into this enomous collage of what we experience as the current moment.

25:15 to 25:30 - I think they used Foley sound...

which pixel is talking?

Dipole antenna: what I don't understand is how can a magnetic field be generated if the circuit is open... because open circuit = no flow of electrons... -> confusion

once more, but with quantum explanation pls )

Good video! This is an invitation to see an artist theory on the physics of light and time! Based on just two postulates 1. Is that the quantum wave particle function Ψ or probability function represents the forward passage of time itself quanta by quanta! 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual!

"Physics is easy! There are only two combinations of these spherical sine wave-front's. They have opposite vector's and spin forming the positron resonance input+0/1-output electron wave-front's concentrically layered like onion's compressing+4-0-4+decompressing eXpanding sphere's dissipating gravity dividing time symmetry, at the same ratio, information is being multiplied by surrounding masses generating electrical potential oscillating volume of mass at the expense of gravitational potential.

25:22 haha so good :)

And when an object accelerates towards the speed of light away from an observer becoming redshifted. And Blueshifted in front of the object compressing the wave-amplitude the shorter the wavelengths this will increase the circular momentum of the waves and the gravitational force!

In this theory objects form their own time by slowing up the rate that time flows relative to their own energy or momentum. This is a process is universal from the largest planet to the smallest creature everything will form its future spacetime geometry by slowing up the rate that time flows relative to its own energy. This can be best seen in plant life in the form of the Fibonacci spiral being visible in almost every type of plant life
