The Speed Of Light

The speed of light in vacuum commonly denoted c is a universal physical constant important in many areas of physics its exact value is defined as 299 792 458 metres per second approximately 300 000 km s or 186 000 mi s it is exact because by international agreement a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1 299 792 458 second.
