I see thank you :) .

Integers I forgot to mention sorry.

Hello everyone ! I got a problem, I can't figure out why when I compute A+B and 2\times (\frac{A}{2}+\frac{B}{2}) the result is sometimes different. Can anyone explain why the results of the two operations are different ? Edit : A and B are coded in binary of course and we compute a binary...

I said in a plasma but it could be in any conducting medium.

Is the relation v_{\varphi }v_{g}=v^{2}=\frac{1}{\mu \varepsilon } always true in a plasma ? Where v_{\varphi }, v_{g} are respectively the phase and group velocity of the electromagnetic wave that is propagating in the plasma.

Yep I figured this out. Thank you for you answer.

There's maybe another way to justify the \frac{1}{2} factor without using Ampère's law ? It's how it was justified in my textbook but I couldn't understand it. Anyone ?

Thank you. And what about the subject ?

Hi everyone ! This is my first post! How can we prove that during the reflection of an electromagnetic wave on the surface of a perfect conductor, the magnetic field \vec{b} acting on a surface element ds is worth half the total magnetic field \vec{B} using Ampere's Law. That is...
