thanks a lot for the help again!

Hi, skin depth tells us that an electromagnetic wave is attenuated but when is it reflected? When i aim light on a mirror its clearly reflected. My question is if its at the border ( right when it goes from air to metal) or at some place inside the conductor (if the latter, then how is a...

Sorry about that, i will try to be more precise next time

Can someone tell me why waves arent coming out of every borders since it radiates in all directions?

thanks a lot!

1. Since skin depth is the attenuation of the wave in a conductor, this means the reflection isen't the incident wave... so what is the reflection? 2. Water doesn't stop light since it's frequency is too high, i saw on forum it's because the big ions can't move fast enought. How can that be...

Ty for the help btw, really appreciate it!

Im trying to understand how an electromagnetic wave makes charges oscillate which makes em radiation similar to the original wave. I was trying to find out about oscillation at its base to understand how it really happens.

Could you tell me how it works generaly the electron oscillation ( no need to be precise but just the general idea ) ty

Sorry for the lack of precisions, let me try again: correct me if I am wrong but i picture the oscillation of the eletron as an harmonic oscillation, and i was wondering what would the force constant be/represent? (If I am completely wrong please tell me, I am not very advanced in physics). ty

Electron oscillate at their natural frequency. I know the force that brings them back is a force of attractrion (Coulomb law) but what pushes them away?

ty !

Can someone tell me if there is a difference in the moving motion between a quantum harmonic oscillator and a simple harmoic oscillator. Also, does anoyone know a good site where i could learn more on quantum harmonic oscillator. ty

When a wave propagates in a materiel (wave has same frequency as natural frequency of the material) there is attenuation. Is the energy absorbed by the materiel?

I read that circulating electrons causes a current ( at an atomique scale ) then that causes a magnetic dipole moment for each molecule. How can that create a general magnetic field which creates a magnetization current density J=rotM ( won't the orientation of the molecule's magnetic field be...
