Best Answer

None. In the absence of an extremely strong gravitational field, like that of a black hole, light will travel in a straight line. It cannot, therefore curve around the world.

In vacuum, in one second light can cover the distance equal to 7.5 times around the world.

How many time a beam of light can travel around the world in one second?

Light could travel seven and a half times around the world in one second.


How many times can light travel around the world in one second?

If light were to go in a circle around the earth it would go around the earth about 7 3/4 times in a second.


7 times light tavels around the earth?

Light doesn't actually go around the Earth; light travels in generally straight lines. But if light DID go around the world, it could go around the world seven times in just less than one second.


How fast does is the speed of light travel around the earth?

Light cannot travel around the Earth, since light travels at a straight line and the Earth is round. The speed of light is 300,000 kilometers per second.


How fast can light travel around the world?

Light travels at 300,000 km/sec. (in a vacuum). That is enough to go 7 1/2 times around the Earth in a second (but note that light has a natural tendency to go in a straight line).


How many times does light go around the world in a day?

Light does not go around the world. It travels in a straight line. For light to go around the world, it would have to periodically redirected using mirrors.


How fast can light travel around the world in a second?

The speed of light in air is approximately 350 meters/second. It is not constant; it depends on pressure, temperature, and humidity.


Is one light year 10 trillion times round the world?

No, it is actually less than that. A light year is about 5.9 trillion miles. Earth's circumference at the equator is about 25,000 miles. So a light year would be equivalent to going around the world about 240 million times.


Why different times around the world?

because the sun sets at different times around the world


How long would it take to fly around the world at the speed of light?

About one-seventh of a second. But it would SEEM like it took no time at all.


A what rate do light waves travel?

300,000 kilometres per second, or 186,000 Miles per Second, or 11,160,000 Miles per minute, or 669,600,000 Miles per Hour (Thats six hundred and sixty nine million, six hundred thousand miles per hour) It's also like 7 times around the world in a second!


How long does it take for light to travel to the earth?

About a second. The circumference of Earth is about 40,075 km. Light travels at about 299,792 km/s. So to find how long it takes to go around 7.5 times, we multiply the circumference of the Earth by 7.5. Then take that answer and divide it by the speed of light, which equals 1.0026 seconds.
