Slow light by Wikipedia Bot 0
"Slow light" refers to the phenomenon where the speed of light is effectively reduced as it passes through a medium, compared to its speed in a vacuum. While the speed of light in a vacuum is approximately 299,792 kilometers per second (about 186,282 miles per second), in certain materials, such as transparent gases, liquids, and solids, light can travel significantly more slowly due to interactions with the material's atoms and molecules.
