Lec 29 | MIT 8.02 Electricity and Magnetism, Spring 2002

[cubeman118]

What level of physics is this? Undergraduate?

[MuppetNLL]

I wish i had teachers like this. Would have made me pay attention.

[theschoolofchuck]

"None of you can say "uy" unless you're Dutch!" Ha Ha Ha, best professor ever...

[Lightsishot]

so i learned this in high school wtf

[kotofu]

rainbows, this is how they work! XD

[sameerpatel105]

i mean on the rotating black and white wheel, not the clown picture thing, that was awesome!

[sameerpatel105]

I DIDNT SEE THE COLOUR!!???! why did it not translate through video?

[Sindrijo]

@sameerpatel105 because of the framerate and frameblending of the video, check out these two videos, you might be able to see it in them, but i recommend just making one yourself, more fun. :)

HOW DO YOU DRAW A DOTTED LINE SO FAST WITH CHALK????

[OKMUNWURX]

@TheJimzhe842 He holds the chalk with a light touch, on a steep angle and lets it hop as he drags it across the slate. Takes practice.

[TheJimzhe842]

@OKMUNWURX actually I've tried it with soft pastel, in art class/ it works!

[junior1984able]

the index of refraction for glass is about 1.60and air 1.00

[freethisone]

the deceleration of refraction due to water is caused by the laser transfer of electrons in the water, and therefore the light is also a carrier of these electron.

but we have already learned that the light has a magnetic, and electric component.

 if the photon passes through small dust particles, ie conductive particles, then a charge is passed to these particles, and they scatter, due to a increase of the spin electron in said magnetic, conducting particles. so we loose photon enrgy.

[bruingineering]

Great stuff!

[johnnyfun26487]

Thank you MIT professors. Thank you MIT so much. Such a wonderful job. I really appreciate it.

[3000moti]

who is he ?

[Hyntime]

this all says that through tv what we think we see could be manipulated. so are we being manipulated from television.

[filipeaa320]

I can say Huygens and I'm not Dutch....=P I'm brazilian....=P

[bigfhead]

i don't see the colors

[100nassar]

Don't you mean that (if dispersive) the bass sounds would be heard BEFORE the violen??

--dale nassar

La.

[kristiankroflin]

Light´s waves, light´s particles, light´s fields, light´s spheres. Where is the problem since it depends on the distance between observer and the observed (also with which kind of "mediator" the observer observes) like it depends on the brain of the observer.

[kristiankroflin]

Newton did assume that theta1 (see from 13:50) stays the same after it has reached the water. How come? This would´ve meant that the light gained energy from where exactly? It wouldn´t only be a prpetuum mobile it would be an energy gaining perpetuum mobile.

[kristiankroflin]

I call those angles theta4 and theta5 by the way.

[kristiankroflin]

The angle between the refracted and the reflected angle is the same, too - not only

the one between the input- and the

reflected beam.

[ammma1991]

thnxxxxxxxxxxxxxxxxxxxxx , youtube the best :O

[psychobollox]

i actually saw red-brown and dark green!

[OGMO11]

if you mean at the disc... the camera picked it up differently

[djahriman]

All thanks to the captured/encoded frame rate.

[Farmani]

Isn't it Sin(Pheta)2/Sin(Pheta)1=V2/V1?

[fingerboy18]

Theta?

[crazymuzikk]

u r rite..if farmani doesnt knw abt theta she has no rite to comment abt such gr8 lecturer..i thnk u got me.

[crazymandx]

lol i feel so stupid compared to him

[humexavier]

charging a solar energy panel without using sun light only using laser light. Gaining solar energy through a energy source like laser fiber optic light can be used for a light source in deep water or in any place were there is no sun light, you can use laser light instead.

[LuvStayn]

You can't get a degree and a good job by watching these for free on youtube no matter how well you understand the concepts.

[fooberdoobs]

@LuvStayn YEAH!!......That's the spirit!!......let's all band together and discourage people from exploring interesting phenomena!!.......you'd rather they were all watching "What, What in the Butt"??........

[evangrogers]

@fooberdoobs you wanna do it in my butt?

[henf5671]

@LuvStayn agreed but at least these videos can make an individual understand the concepts inside and out before they take a real class and ace it just like that. then these people can eventually get a degree. by the way, i'm not one of those people. if i watched these videos first and took the class, it would take me forever to graduate. i take the course without watching the videos first. but i may use these videos as a supplement to my class to help me further my understanding on a topic.

[AmishUnicorn]

@LuvStayn that's not the point...

[reynoldslights11]

TO  boring.

[webovisionca]

kids are paying 1000$s of dollars to go to school and its all free on youtube. that's friggin hilarious.

[majuicee]

You cant put it on your CV though =/

[ChomuSclavus]

DUDE! When I searched for "OK Go here it goes again orchestra," why was THIS the top result?!

[samamies88]

i searched for "condition zero music remix", but i found this... WTF

[pcmatt2000]

I like his lectures. Every time I wondered how something applied, he showed us.

[edudrepus]

The ending was super killer!

[MajorUtah]

Ahhh, sweet wine for the mind... this rocks..

*XD

[ModestAggrandizement]

Swoosh, way over my head.
