Slowest light
Did you know?
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… WebbJanuary 2001 In January 2001, two groups of US scientists announced that they had slowed down light itself to a dead stop. Usually light travels at 300,000 km per second 186,000 miles per second. light is slightly slowed naturally as it passes through a denser medium, eg water or glass.
