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 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.
How many times can light go around the world in1 second?
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 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 long would it take light to traver around the world?
Light travels at approximately 186,282 miles per second. The circumference of the Earth is about 24,901 miles. Therefore, it would take light approximately 0.133 seconds to travel all the way around the Earth.
Who was the second person to travel around the world?
Sir Francis Drake
What does light have to do with science?
Light's contribution to Science was when the scientists realised how fast light can travel around the world.
How many times can light travel around the world in one second?
The circumference of the Earth is approximately 40,075 kilometers. Light travels at a speed of about 299,792 kilometers per second in a vacuum. Therefore, light can travel around the Earth about 7.5 times in one second.
How fast does the world travel in space around the sun?
About 30 kilometers / second.
How long does it take lightning to go around earth once?
The radio waves from a lightning stroke travel at the speed of light, you can hear them as clicks on a long-wave radio, and they travel round the world in 1/7th of a second.
Why is sir Francis drake's voyage important?
he was the second person to travel around the world
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.
