Web17 aug. 2016 · 6. Let's state some basic facts. Whenever speed of light is given as 186, 000 m i / s or 300, 000 k m / s, that's its speed in a vacuum. In the real world we use copper cable or fibre optic (glass) to conduct electricity or light. Copper slows electrical current to about 70 % of the speed of light and glass slows light by about the same.
