The SI metre is defined such that the speed of light in a vacuum is exactly 299,792,458 metres per second. This equates to 186,282.4 miles per second.
The figure is 186,282 miles (299,793 kilometers) per second
Not sure about lidht but light travels at approx 186200 miles per second.
A meter is defined as the length light travels in 1/299,792,458th of a second. This is because light travels at 299,792.458 kilometers per second.
The "official" speed of light in a vacuum is 299,792,458 metres per second So in a millisecond - which is one-thousandth of a second - it will travel 299,792.458 metres. The Imperial equivalent of that is 186.2824 miles, or 186 miles, 495 yards, 5 inches.
About 1100 feet per second, which is the speed of sound.
In free space, light travels at 186,282.397 miles per second, so in one minute it has travelled 11,176,943.82 miles. [See Link]Mhmm. Oh yeah, sorry. It is.
Light travels at 299,792.211 km per second in a vacuum.
Light travels at the rate of about 300,000 km a second.
The speed of light is not dependent on how long time it travels.
it travels at about 128,609 miles per second!
light travels very fast! it travels in the form of waves.
The speed of light in empty space is 300,000 kilometers per second. That's how fast light travels. The direction, or where it is headed, doesn't affect the result.
Please note that the speed is the same for 1 second or for 1 hour or whatever. Light travels 300,000 km per second, or 300 million meters per second.
Ultraviolet light travels at the speed of light, approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum.
Please be more specific.
Light travels at about 186,000 miles per second, or 300,000 kilometers per second, in free space.
Light travels at 186,282 miles per second in a vacuum.
Light travels in straight lines. Light goes very very fast. About 300,000 km per second. Ima chargin' muh lazers. It travels as electromagnetic waves.
