光速实验在物理学史中占有重要地位.这不仅是因为它需要精确的实验手段,对光学的发展起了推动作用;也不仅仅因为它有力的支持了机械波动说,而给机械微粒说以致命的打击。重要的是光速实验打破了光速无限的观念,解决了长期存在的所谓以太漂移的疑案,为建立近代物理基本理论之一的相对论,提供了一块颇为重要的基石. The experiment of light speed occupies an important place in the history of physics, not only because it requires precise experimental means to promote the development of optics, not only because it strongly supports the mechanics of fluctuations but also to the mechanical particles Deadly blow. What is important is that the speed of light experiment breaks the notion of infinite speed of light and resolves the long-standing suspicion of so-called ether drift, which provides a rather important cornerstone for the establishment of one of the basic theories of modern physics.
