What is EMCsquare?
the measurement of energy mass speed of light
What is the SI measurement of light?
There is no "measurement of light". The units used depend on what you want to measure: its speed, frequency, wavelength, energy per photon, etc.
What is a exact speed of light in a vacuum?
The speed of light is 299 792 458 m s-1.This is one of the very few exact physical constants; it is so by definition.This enables the meter to be determined by it and the second.
Can you find the exact measurement of a cylinder?
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?

The speed of light is what in space?
The speed of light in a vacuum (space) is about 3x10^8 m/s. The most accurate measurement is:
What is relative wind speed?
Relative for starters means exact or close to. Wind Speed is how fast the air is blowing. It other words, this would mean an estimate or exact measurement to the Wind Speed.
How did physicist calculated the prise measurement of the speed of light?
