@henpen is some sort of relativist or something... ;)

anonymous · Answer

its not relativity

the speed of light is constant through a vacuum

it decreases as it travels through a medium( like air or water), henpen is correct

anonymous · Answer

@razakhan78  Usually you talk about "velocity of light through some medium"  (for example, empty space or water or atmosphere

anonymous · Answer

I know @henpen is right... just a [bad] joke :)

anonymous · Answer

Actually, I was being a little facetious:|dw:1348258414479:dw| And anyway, in water it does actually travel at the speed of light, it just doesn't go in straight lines.

anonymous · Answer

well, light travels at the speed of light...  that's a truism.  It all depends on what this question is trying to accomplish... doubt it's a physics question... sounds more like early science

anonymous · Answer

also, think we lost the original question asker... oh well

anonymous · Answer

I was just playing on the word 'velocity'. General relativity makes things confusing.|dw:1348258676696:dw|
