Slowest light speed
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… Webb13 jan. 2024 · It is the wavefront that slows down, and that is why we use classical phrases like the speed of light in a medium slows down. Depending on the natural frequency of the atom and the frequency of the wave, the emitted photons will change phase when compared to the other, unaffected photons. Therefore, it either falls backward or forward …
