Why does light travel faster in empty spaces?

Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).


Is it true or false the second postulate of special relativity says that the speed of light in empty space depends on the motion of the source or of the observer?

False. The speed of light in empty space is a constant, independent of the motion of the source/observer. An observer travelling towards or away from a light source at 99% the speed of light would measure light going the same speed as an observer stationary relative to the light source.


Who discovered that electromagnetic waves can travel through empty space at the speed of light?
