Answer by Shivam jadon for Why does larger permittivity of a medium cause...

This can be understood by the fact electric field inside the conductor is zero so instead of conductor if we take dielectric will polarized and form dipole field opposite to applied electric field and...

Yet another way, in terms of an ensemble of oscillating charges, to see this: the overall effect of incident light is to induce the charges to oscillate with a phase delay (because they react) which...

If I can expand a little bit on Sofia's answer the polarization of the medium opposes time variations in the electric field thus slowing down the phase velocity of the wave.This can be seen from...

Answer by Sofia for Why does larger permittivity of a medium cause light to...

An intuitive explanation why in dielectrics the phase velocity is slowed down, is that the dielectric opposes the field. The dipoles in the dielectric arrange themselves with the positive pole toward...

Why does larger permittivity of a medium cause light to propagate slower?

I was wondering about what physically happens when light is transmitted through a non-magnetic medium. Specifically, I’m trying to visualize how materials slow down light as the electromagnetic wave is...
