300,000 km (186,000 mi)
299,792km
One meter is the distance travelled by light in vacuum in 1/299 792 458 second.
It is the distance travelled by light in one year at a speed of 186,000 miles per second
1 light day is a distance.
Only one. Because Light year is a messure of distance not of time. Light year is the distance travelled by light in one year.
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.
# The distance that light travels in a vacuum in one year, approximately 9.46 trillion (9.46 × 1012) kilometers or 5.88 trillion (5.88 × 1012) miles.
Light is the fastest thing we know...nothing is faster than light. So the distance travelled by light in 'some' time will be the greatest. And as the distances between stars etc is huge, Light Years are used as it is the distance travelled by light in a year. And nothing can travel more distance in one year. So light years are used.
No, that would be a light-second. A light year is the distance light travels in one year, which is 5,865,696,000,000 miles (5.87 trillion miles). Or 946,080,000,000,00 light travel 300,000 km per second
In a vacuum, light will travel 299,792,458 meters in one second.
1 light year equalls distance travelled by light in one year which equalls velocity of light * 1 year( 365.25 * 24(hour) * 60 * 60 ) which equalls value 9.467 * 10 power 15m.
the distance light travels in one year. light travels at around 300,000,000 metres per second. 1 year has 31,556,962 seconds in it, therefore a light-year is approximately 9,467,088,600,000,000 metres.
A light-second is the distance light travels in one second in a vacuum. That equates to 186,282.4 miles per second.
