Primarygun Posted September 5, 2004 Share Posted September 5, 2004 When light passes a medium, it's speed decreases. Is the acceleration of light decreased? Link to comment Share on other sites More sharing options...
Thales Posted September 5, 2004 Share Posted September 5, 2004 Light has no acceleration/deceleration because the speed of light is constant. the illusion of its speed changing in differing medium is to do with phase velocity. Do a quick google for futher information. Link to comment Share on other sites More sharing options...
Primarygun Posted September 7, 2004 Author Share Posted September 7, 2004 What's the keywords? Speed isn't slowed down when we look at it outside? Link to comment Share on other sites More sharing options...

5614 Posted September 7, 2004 Share Posted September 7, 2004 light can be slowed down in more dense materials: http://news.bbc.co.uk/1/hi/sci/tech/1124540.stm i'got a better link at home, but i can't access it now, i'll post it here later.

5614 Posted September 7, 2004 Share Posted September 7, 2004 heres the site: http://www.newscientist.com/news/news.jsp?id=ns9999340 its also a more reliable source for scientific data than the BBC Link to comment Share on other sites More sharing options...
swansont Posted September 7, 2004 Share Posted September 7, 2004 light can be slowed down in more dense materials Note that that was done in a dilute vapor - hardly a physically dense material. It's optically thick because the light is on resonance. Link to comment Share on other sites More sharing options...
