Schlegel's photon clock theory

  • 44 Accesses

  • 1 Citations


In a recent paper, Schlegel states “... the photon clock when interpreted as a device for showing the Lorentz transformation of time does actually involve a violation of basic relativity principles.” His conclusion is false, and is based on an incorrect analysis of the photon clock in two reference frames with relative motion. The purpose of this note is to present a corrected analysis and show that such an analysis is consistent with basic relativity principles.
