Light speed on earth
WebIn terms of seconds, light travels at around 300,000 kilometers per second or 186,000 miles per second in a vacuum. In water, the speed of light is slower, at 225,000 km / 139,808 mi per second, and 200,000 km / 124,274 mi per second in glass. It seems that nothing can be faster than the speed of light.
