Of course, microwaves travel in straight lines, not around the Earth, but just like any other electromagnetic wave, like light or X-rays, the speed of microwaves is about 300,000 kilometers per second. That distance corresponds to roughly 71/2 times the Earth's circumference.
light can travel around earth about seven times
Light travels around the Earth approximately 7.5 times in one second, given that the Earth's circumference is about 40,075 kilometers and light travels at a speed of approximately 300,000 kilometers per second.
About 300,000,000 meters per second - enough to go around the Earth 7.5 times in a single second.
The speed of light in a vacuum is approximately 299,792 kilometers per second (186,282 miles per second). Light can travel around the Earth's equator about 7.5 times in one second.
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.
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).
It is most likely to begin bubbling and grow around 5 times in size. For a demonstration you can go to you tube and type in soap in your microwave.
That's 4 times as much as going once around the Earth. The distance around the Earth is about 40,000 kilometers, or 40 million meters.
55 times per second. (globaly)
8.6 million times a day or 100 times a second.
At any given time there are roughly a couple thousand thunderstorms traversing the earth. Lightning flashes around 40 times per second given this research, and hence, strikes the earth roughly 150,000 times an hour and over a billion times a year.
Its about 120,000 km in diameter, compared with Earths 12,700km diameter. So its diameter is about 9.5 times as big as the earths. But when you look at the volume (a three dimensional measurement of size) it has a volume of around 763 times that of earth.
