The speed of light is about 300,000 miles per second in a vacuum. In air, it is about 90 kilometers per second slower. Group velocity experiments back it up.
Light travels 3E8m/s x40inches/m = 12 Billion inches/second.
the speed of light = 670 616 629 mph
The speed of light in vacuum is 299,792,458 meters (186,282 miles) per second.
"Speed per inch" is not a unit of anything, and it has no physical meaning.
Light travels at a speed of 186,000 miles per second, in a vacuum.
The speed of light is 300,000 kilometers per second. If you multiply that by 60, you have the speed in kilometers per minute.
Electromagnetic radiation, such as light, travels at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is considered to be the maximum speed limit in the universe.
Light always travels at the speed of light. The only time that's 299,792,458 meters per second is when the light is in vacuum.
Whether the car is moving or not the speed of light is constant. It is travels at approximately 300,000 kilometres per second
Light is much faster then the speed of sound. Sound travels at a speed of about 768 Miles per hour, when light travels at a speed of 186,282 miles per SECOND.
In vacuum it travels at 299,792,458 metres per second.
Light travels at a speed of 186,000 miles per second, in a vacuum.
Light travels at a speed of 186,000 miles per second or 669,600,000 miles per hour. Light travels somewhat slower when it is "in" something, such as glass or water.
