(c0) = 29 979 245 800.00 019 centimeters per second (cm/sec).
Lightning's maximum speed is just short of
30 centimeters per one-million-th of a second.

Asked in Physics, Speed of Light
How many times greater is the speed of light than the speed of sound?
The speed of sound in air is about 300 meters per second. (320 is closer still). . . The speed of light in a vacuum is 300 000 000 meters per second. So the speed of light in a vacuum (in air it is only slightly different) is about one million times the speed of sound in air. ...
Asked in Science, Speed of Light
Is there a formula for working out the speed of light?
Answer: The speed of light was determined through experimentation, such as the timing of moons passing behind Jupiter. Many formulas are based upon the speed of light, but that number had to be determined beforehand. Light travels 299,792,458 meters per second (or 186,282.397 miles per second in a vacuum. Answer: Yes, the speed of light can be deduced from the electrical properties of empty space. However, in practice it is more accurate to measure the speed of light. ...

What value must you know to calculate how much a light-year represents?
A "light year" is the distance that light travels in one year. Light travels so fast that the speed of light is measured in miles per second or km per second. You probably already know how many seconds are in a minute (60), how many minutes are in an hour (60), how many hours are in a day (24), and how many days are in a year (365.24). So if you knew the speed of light, you could multiply all those...

How a monitor uses pixels to create an image?
Well acrecing to my calcutlations it uses many pixel a second at faster than light speed making a black hole Well acrecing to my calcutlations it uses many pixel a second at faster than light speed making a black hole Well acrecing to my calcutlations it uses many pixel a second at faster than light speed making a black hole ...
How many miles does light travel in 1 microsecond in a vacuum the speed of light in a vacuum is 186000 miles per second?
Since a microsecond is a millionth of a second, just divide the distance light travels in one second, by a million. ...
Asked in Science, Speed of Light
What is the speed of light energy in solids?
The answer depends on the solid.In glass (pyrex) it is approx 204,000,000 metres per second. In heavy flint glass its speed falls to 156,000,000 metres per second. In diamond it is 124,000,000 metres per second. In lead, for example, it is 115,000,000 metres per second but it does not travel very far before it is stopped through absorption. Also, in some crystals the speed of light depends on the direction of travel. ...
How many times can the speed of light travel the world in a second?
If light were to go in a circle around the earth it would go around the earth about 7 3/4 times in a second. ...
Asked in The Moon, Black Holes
What is the size of a light year?
It is hard to measure because light travels at such a high speed in one second that in one year, it would be too large a number to calculate. Try finding our the speed of light per second or minute and using conversions to calculate how many miles it would be. :) ...
