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.
To calculate how long it would take for light to travel around the world, we need to consider the circumference of the Earth and the speed of light.
The equatorial circumference of the Earth is approximately 24,901 miles (about 40,075 kilometers). The speed of light in a vacuum is approximately 299,792 kilometers per second (about 186,282 miles per second).
Now, let's calculate the time it would take for light to travel around the Earth:
Time = Distance / Speed of light
Using kilometers:
Time = 40,075 km / 299,792 km/s
Time β 0.1337 seconds
Using miles:
Time = 24,901 miles / 186,282 miles/s
Time β 0.1337 seconds
Therefore, it would take approximately 0.1337 seconds for light to travel around the world once, assuming a straight path through a vacuum. This means light can circumnavigate the Earth nearly 7.5 times in just one second!
Light does not travel around ... light travels in a straight l ine ... unless there is a massive gravitational source. But this question is lacking an object in the sentence, so I really dont know what you are trying to ask.
Light from the Sun takes about 8 minutes to reach Earth. Light from the stars can take several years and up to billions of years.
To reach earth from the sun, light takes about 8.3 minutes.
To circle the earth once, light takes 0.13 seconds, so light can circle the earth about 7.5 times per second.
It will take about 0.140 seconds
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
4.25 years, because it is 4.25 light years away.
Light can travel once around the earth in .00013358 seconds.
8min 19s
8 minutes, as that is the time it takes for the light from the sun to travel to the earth.
It takes Light 8 Minutes to get from the Sun to the Earth.
Light take approximately 8 minute 20 seconds to travel from the sun to the earth.
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
about 81/3 minutes
Just over 8 minutes.
Roughly 1.28 seconds (rounded)
