Physics 46 Maxwell's Equations (2 of 30) Speed of Light

In this video I will use Maxwell's equations to calculate the speed of light.

I had always wondered what the permitivity terms meant. Thank you for clarifying that. Amazing that the two are related to speed of light!

excellent presentation talent, u r the real ' Mac Gyver, dear sir, wish u all happiness..

At 1:47: "[Mu sub-naught & epsilon sub-naught] are properties of free space out there in the universe. The whole universe is filled with space, and it [magnetic permeability & electrostatic permittivity] controls how fast magnetic fields and electric fields can interact with each other and ... with charges and current."

How can be scientist like you have only few thousands of viewer and other silly peoples have a millions of viewers?
That is absurd!!!

[valeriereid]

Wonderful! Thanks for these excellent lectures.

[anasghaffar]

I wish you had derived that equation for speed of light!

[tammychong]

You are amazing. Can you do some videos to explain Fresnel equations? It will be greatly appreciated

I think we know that there is electric flux around an electric charge & its density decreases outward as per inverse sq. law, although we don't yet know what this flux is made of. Do we have any evidence of a force field around single charge? Presesnce of a force field is established by using a test charge. By bringing in a test charge we are actually allowing flux of test charge to interact/interfere with flux of main charge. This only proves that interaction or interference between fluxes produce force fields.

amazing but Where this Relations come from? Why E=Kq/r² and
B=u I /( r . 2Pi ) ?
Why one of this Related to r and other one related to r² why B related to 1 / 2pi ??

How they calculate epsil (Permittiviteit) and the other

[juanmf]

So it’s not a speed at all. But a rate of induction, of the MEDIUM.

[kamiljedrzejewski]

How did we get the constants ε0 and the other one

[TheSalto]

The speed of light does not depends from the speed of the observed from the observer.
Why ?
What this means ?

ehi Farrrraday, how can one elaborate and expose a big explanation based on the very important and accurate values of mu and epsilon (permittivity end permeability) and say nothing about how this two fondamental pillars did being obtained/measured? Jesus Christ did gives it to us?
