Light from a moving source also travels at 300,000 km/sec (186,000 miles/sec).
What speed is light speed?
Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the speed of light, would circum-navigate the equator approximately 7.5 times in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would cross the continental U.S. once in 4 hours.
To be exact, it is 299 792 458 m/s and not 3*10^8. It is speed is a relative theory, where many a things are taken into account like the medium it is travelling and the distance between them. And according to the calculations of light traveling from Sun to Earth, it is believed to be the figure mentioned above.
What is the speed of light in simple terms?
The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c," or light speed.17 mai 2023
