WebFeb 17, 2024 · The second wrong idea about why the light slows down in a medium is that light is not scattered, but rather that it is absorbed and re-emitted by the atoms. Again, … Slow light is the propagation of an optical pulse or other modulation of an optical carrier at a very low group velocity. Slow light occurs when a propagating pulse is substantially slowed by the interaction with the medium in which the propagation takes place. Group velocities below c were known to be possible as far back as 1880, but could not be realized in a useful manner until 1991, when Stephen Harris and collaborators demonstrated electromagn…
