reflection of light, elastic collision, Michelson interferometer
Considering that the speed of light does not change after reflection, Michelson obtained the theoretical fringe shift of 4.00E-01 for his interferometer. Considering the reflection of light as a mechanical phenomenon, so that the speed of light changes after reflection, the theoretical fringe shift is 2.00E-05. This magnitude of the fringe shift is not experimentally observable. Therefore, the reflection of light as a mechanical phenomenon explains the null result of the Michelson–Morley experiment.
