Opposing hypotheses of the reflection of light applied to the Michelson interferometer with a particular geometry

The derivation of light paths in the Michelson interferometer is based on the hypothesis that the incident speed and reflected speed of the wavefront of a ray of light are equal in the frame at absolute rest. In this case, the Michelson‐Morley experiment predicts a fringe shift of <mml:math display="inline"> <mml:mrow> <mml:mo> </mml:mo> <mml:mn>0.40</mml:mn> </mml:mrow> </mml:math> . With the hypothesis that the incident speed and reflected speed of the wavefront of a ray of light are equal in the inertial frame of a mirror at the instance of collision, the Michelson interferometer with a particular geometry predicts zero fringe shift, which is in agreement with the result of the Michelson‐Morley experiment.
