That depends on what kind of material it's in.
In vacuum ... no material at all ... the speed of light is 299,792,458 meters (186,282 miles) per second.
In physical materials, like water, glass, or jello, it's less.
Light travels approximately 0.3 millimeters in one trillionth of a second.
How far does light travel in one hour
It is the distance travelled by light in one year at a speed of 186,000 miles per second
Light travels approximately 186,282 miles (299,792 kilometers) in one second.
0.3 cm a) one trillionth of a second= 1.0x10^-12 b) light travels at = 3x10^8 meters per second b/a= 0.0003 meters = 0.3 cm actually 0.03cm or 0.3mm or 300µm
29.782Mph
In a vacuum, light will travel 299,792,458 meters in one second.
Light can travel about 5.88 trillion miles in one lightyear.
The information about a light-year is not relevant to answer this particular question. To find out how far light goes (in a vacuum) in any specific time, simply multiply 300,000 (km/second) by the number of seconds.
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
Yes, it does.
Light could travel seven and a half times around the world in one second.
