Yes, it does.
In a vacuum, light will travel 299,792,458 meters in one second.
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.
Light could travel seven and a half times around the world in one second.
Nope, 186,282 miles per second.
Light travels approximately 0.3 millimeters in one trillionth of a second.
light can travel around earth about seven times
300000 km/second
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
Light travels approximately 299,792 kilometers in one second. This is equivalent to 299.792 megameters or 0.299792 gigameters per 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
If there is an unobstructed path, it can continue traveling practically forever.
Light travels at a speed of about 186,282 miles per second (299,792 kilometers per second). That means light can travel around the Earth about 7.5 times in one second! It's the fastest thing in the universe that we know of.
