討論:光速不變原理
isn't that the speed of light travelling in vaccum? light always slows when travelling through media such as glass... I believe there is a better definition to this "principle" (what's the name of this principle in english?) please refer to [1]
Ha, I don't know if I would write it this time myself....:) --Johna 02:18 2005年6月26日 (UTC)
- 在引力場中光速應該同樣是不變的。--彳亍 05:33 2005年6月30日 (UTC)
