Experiment on the reflection and emission of light.

Suppose the velocity of light is independent of the source velocity. In that case, the reflection of light as a mechanical phenomenon predicts a zero fringe shift when applied to the Michelson interferometer with a particular geometry, a 0:40x10-4 fringe shift when applied to the Michelson interferometer presented in the Michelson–Morley experiment, and a 210 fringe shift when applied to the interferometer presented in this study, which contradicts the zero fringe shift experimental result. If the velocity of light depends on the source velocity, the reflection of light as a mechanical phenomenon predicts a zero fringe shift for all three experiments. The study of emission, propagation, and reflection of light as mechanical phenomena concludes that the optical phenomena are in an inertial frame as in the frame at absolute rest and cannot prove the motion of an inertial frame in which sources and mirrors belong to that inertial frame.
