How many times could light travel around the circumference of the Earth in 1.4 second? Let the circumference of the Earth be 24,000 miles.
Doesn't light travel in straight lines?
time for one 24,000mile trip= distance/speedlight
To find out how many times light could travel around the Earth in 1.4 seconds, we need to calculate the distance light can travel in that time and then divide it by the circumference of the Earth.
The speed of light in a vacuum is approximately 186,282 miles per second.
To determine how far light can travel in 1.4 seconds, we multiply the speed of light by the time, like this:
Distance = Speed × Time
Distance = 186,282 miles per second × 1.4 seconds
We can calculate this: 186,282 × 1.4 = 260,395.2 miles
Now we divide the distance light can travel in 1.4 seconds by the circumference of the Earth to find out how many times light can go around:
Times = Distance ÷ Circumference
Times = 260,395.2 miles ÷ 24,000 miles (circumference)
We can calculate this: 260,395.2 ÷ 24,000 = approximately 10.8498
Therefore, light can travel around the circumference of the Earth approximately 10.8498 times in 1.4 seconds.
