In one picosecond, which is one trillionth of a second, light can travel approximately 0.3 millimeters in a vacuum. This distance is equivalent to about the width of a piece of paper.
Light travels approximately 186,282 miles (299,792 kilometers) in one second.
Light travels approximately 186,282 miles per second. So, in 20 seconds, light would travel around 3,725,640 miles.
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.
Light waves move through a vacuum at their maximum speed, 300,000 kilometers per second or 186,000 miles per second. Which makes light the fastest phenomenon in the universe. Light waves slow down when they hit or pass through something.
Light travels approximately 0.3 millimeters in one trillionth of a second.
In one picosecond, which is one trillionth of a second, light can travel approximately 0.3 millimeters in a vacuum. This distance is equivalent to about the width of a piece of paper.
Light travels at a speed of about 299,792 kilometers per second. In half a second, light will travel around 149,896 kilometers.

As far as light can travel
Speed doesn't travel. Light travels.Light goes about 300,000 km in a second; in an hour, it goes 3600 times as far, since an hour has 3600 seconds.
Light would travel just less than 1 foot in a billionth of a second, or roughly 11 3/4 inches.
Light travels approximately 186,282 miles (299,792 kilometers) in one second.
Light travels at a speed of approximately 186,282 miles per second. Therefore, in two seconds, light would travel around 372,564 miles.
It is the distance travelled by light in one year at a speed of 186,000 miles per second
How far does light travel in one hour
A light-year is a measure of distance, just like a foot, a meter or a mile. A measure of distance is not considered to travel. If the question is how far light travels in one second, the answer is 299,792.458 kilometers, or about 186,286 miles. The speeds noted refer to light moving in a vacuum.
