Well it won't as light can't turn only go straight from its source.
It almost could if you used fiber optics, and then if you used fiber optic cable the loss in the cable would have the light completely gone long before the light made it around the world.
But the math Speed of light = 299,792,458 METERS PER SECOND
Circumference of the Earth = 40075.16 km
Math MPS to KMPS 299792458 / 1000 = 299,792.458 Kilometers per second
40075.16 km / 299792.458 kmps = .1336 seconds

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.

How do you know the speed of light is correct since a light wave has no beginning or end it would seem impossible to measure?
Turn your flashlight on and off. The light wave begins and ends. The light wave from your flashlight will take 1 nanosecond to travel one foot from your flashlight.
