PHYS 101/102 #1: Electromagnetic Waves

[rfengr]

Thanks to Microsoft power point, we don't see any of these cool toys in class anymore. Instead we see some poorly made animations (if we're lucky).

[TheStarryboy]

awesome stuff. My professor recommended it to me :)

[jjclassjj]

some really good stuff here

[Concienciafractal]

Pido al que pueda que haga la traducción o el subtitulado en Español. Gracias!

[jayejayeee]

some sweet info here

[freemanx2x]

Something i don't get...When the electric field is maximum in the antenna, the current and so the magnetic field should be at minimum ( so in the transmitted wave). So why the electric field and the magnetic field are shown that they are in phase?

[sudhansumtripathy]

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

[SuperCajuan]

he's my dad

[muhammadzahmad]

this is worth watching

[h2opower]

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

[thebigfootme]

the video is great!

[weweallthewayhome]

yay SPARKS!!!

[omalrafa]

this video is great!

[007MrYang]

Im 17 and this is fascinating. Can't wait to actually learn it!

[GeneralBB3]

So Cool

25:20 = silly and lol.

I did quite a few of these experiments in my Conceptuals Physics class. Thanks.

[iloveflyingac]

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...........

[asadtempestian]

@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".

[teflondon91]

15:41 -- great example of mismatched polarization.

[CornellUniversity]

@teflondon91 Thanks, we'll bookmark that spot on our site. :)

[teflondon91]

@CornellUniversity Thanks for replying to my comment. I found it funny that he had a piece of Bakelite! When was this filmed?! bakelite was used extensively in the early years of radios and general electronics; it was one of the first plastics ever discovered.

[professional80]

I was there!

[JesusWASdarkSkin]

Thanks professor

[muzammilali007]

Practical demonstration just makes everything so easy. thank you for the easy explanation.

[kj6bbs]

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

[lonestarlulu]

this was so great, really helped me to understand

[1979Guts]

more current as in maybe using some graphics, better video resolution. sheesh.

[KakHazhar]

25:22 haha so good :)

[JaimeBayes]

@KakHazhar Yeah, poor guy....that was funny

[moadbahron]

@KakHazhar speed of light could be deadly.

[gmcjetpilot]

Better lighting, close up of the apparatus and more detailed description of the circuit would be an improvement. Love the old demos.

I think he was getting kinky at 6:35

[solo2wolf]

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

[1979Guts]

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

[gmcjetpilot]

@1779Guts

"IT wold be great...do a more current version of this."

The understanding of the physics has not changed in almost 270 years.... so what is a "more current" version mean? HD video? Better fashion and hair style? Please.

[TuscaniManiac]

gr8 vid thx !

[Junio6481]

I wish I had found these videos back when I was taking these subjetcs in school. Sad to see not many coments :p
