The speed of light is 186,000 miles per second (approximately 300,000 kilometers a second).
Light goes about 300,000 kilometers in one second. (in a vacuum)
One Light Year
299,792,458 meters per second or 186,282 miles per second in a vacuum. Light slows down in air, more so in water.
The speed of light is about 183,000 miles per second, or just under 300,000 kilometers per second. Radio transmissions, which travel at the speed of light, can go from the earth to the moon in under two seconds, but it would take them almost nine minutes to reach the sun. As far as distance, no one has ever theorized that light stops traveling, if unimpaired by a solid substance. It's presumed that it can travel to the known edges of the universe, but it can take it billions of years to get there.
It's how far does light go in 17 minutes . . . . 305.7 million km, equal to the diameter of the Earth's orbit.
Light years, are basically how far would does light travel, at roughly 186,000 miles a second, if it were to go for a year.
Light travels around the Earth approximately 7.5 times in one second, given that the Earth's circumference is about 40,075 kilometers and light travels at a speed of approximately 300,000 kilometers per second.
Light anywhere travels about 186,000 miles in one second. It takes light 8 minutes for sunlight to reach Earth.
I suppose you mean how far it can go. There is no limit how far it can go, but any light will get weaker as it gets spread over a larger space. That doesn't depend on the color of the light.
Light travels 186,000 miles per second, which is equal to about 5.87 trillion miles in one year. This calculation is done by multiplying the speed of light by the number of seconds in a year (60 seconds/minute * 60 minutes/hour * 24 hours/day * 365 days/year).
A millionth of a second is one microsecond. It is the length of time a beam of light, traveling about 3 x 108 meters per second, will take to go about 300 meters.
