My own opinion is that there are various models for what light does, and
if we insist that light is emitted and reabsorbed, then we really are
saying that the particle model for light is correct and the wave model is
false. After all, it is *photons* which are absorbed and re-emitted.
Light wavelength is far larger than the spacing between atoms, and I
cannot see how "absorbed/emitted" applies to the EM fields or to EM waves.
Instead, the transparent material acts as a non-vacuum medium, having an
altered propagation velocity. If we insist on "absorbed/emitted", then we
fly in the face of wave/particle duality.
