The speed of light cannot be measured IN A WAY. However it travels at 1,079,252,848.8 miles per hour or 299,792,458 meters per second. It cannot be measured however the numbers I showed is one way. Light cannot have a specified measurement, unless the light source is big or small etc...

When was the speed of light measured?
It was measured in 1887.
What is the speed of light in hurtz?
Hz (hertz) is a unit of frequency, not of speed.
Is the speed of light a law or theory?
The speed of light is a number. It was a theory before it was measured. After it was measured, and the prediction was found to be correct, it was no longer a theory nor a hypothesis. It became a "physical constant".
When did scientists attempt to measure the speed of light?
Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?
Do neutrinos travel at the speed of light?
No, neutrinos have been shown to have a small non-zero mass. They can't get to c (the speed of light in a vacuum). The only thing a supernova can eject at the speed of light is photons. Update: Recently an experiment has measured neutrinos traveling above the speed of light. An explanation is yet to be offered.
What is the speed of gravit?
It's never been measured, but it is assumed to be the same as the speed of light.
How was the speed of light measured?
In light speed.
What is the speed of gravitional force?
It's never been measured, but it is assumed to be the same as the speed of light.
Why does light have a defined speed?
Because it takes light time to move from one place to another. The time it takes to move a measured distance has been measured, and its speed has been found to be a certain number. A contest was held to name that number, and the winning entry was "The Speed of Light".
