Light travels at a speed of approximately 299,792 kilometers per second in a vacuum.
The closest is the speed of light at 299,792,458 kilometers per second.
speed of light
Speed is calculated by dividing distance by time, so: 100m / 20s = 5 m/s The object is travelling at 5 metres per second. Or, it is travelling at 7200 kilometers per second.
mercury travels at about 48 kilometers per second, or 172,000 kilometers per hour.
Light travels faster than sound. Light travels at a speed of about 186,000 miles per second (300,000 kilometers per second) in a vacuum, while sound travels at a speed of about 1,125 feet per second (343 meters per second) in air.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
Light travels at the rate of about 300,000 km a second.
Electromagnetic energy
Light travels approximately 186,282 miles (299,792 kilometers) in one second.
Speed is the distance an object travels per unit of time. It is calculated by dividing the distance traveled by the time taken to travel that distance. Speed is usually measured in units like meters per second (m/s) or kilometers per hour (km/h).
Light travels approximately 983,571,056 feet in vacuum in the time it takes sound to travel 1100 feet in air.
