We present an analytic study of light propagation in a simple Michelson–Morley interferometer as observed by inertial observers to understand any connections among classical physics, optical physics, and special relativity. To that end, we develop coordinate transformations of wave propagation as observed in inertial frames (i.e., non-accelerating reference frames). We find that relativistic and other effects appear naturally as a result of finite light speed. Such effects include wavefront tilt relative to the normal of energy flow with the wavefront normal tilting relative to the Poynting vector.

关于通过古典物理学的相对论效应。

我们对惯性观测器观察到的简单迈克尔逊-莫雷干涉仪中的光传播进行了分析研究，以了解古典物理学，光学物理学和狭义相对论之间的任何联系。为此，我们开发了在惯性系（即非加速参考系）中观察到的波传播的坐标变换。我们发现由于光速有限，相对论和其他效应自然而然地出现了。这样的影响包括波前相对于能量流法线的倾斜以及波前法向相对于Poynting向量的倾斜。
