The Propagation Velocity of Electromagnetic Waves

February 9, 2012 -

1. You have done a remarkable work so far to expound the principles of electrostatics. I have to re-read all the posts and absorb.
Here you have found the speed of light. That is based on two other constants. I have to read the older posts to see if those constants were calculated from from principles. Otherwise, there is some circularity here.
I am still not sure whether you proved in all these posts Maxwell’s equations from vector calculus alone (generalized Stokes’ theorem). If that is the case, it proves the power of vector calculus.
No matter the questions that linger in mind, what you done relating calculus and electrostatics is truly wonderful. Congratulations! I hope you continue this effort.

2. I didn’t get into how $\epsilon_0$ and $\mu_0$ were calculated, but in fact they are determined from laboratory experiments which are specifically concerned with electric or magnetic phenomena, and not with light as such.

4. I need a formula to calculate the question below or the answer.
A 5 GHz plane electromagnetic wave is propagating in a polystyrene block(E=2.5). Find the velocity of propagation. Take E0=8.85×10^-12
U0=4pix10^-7
