Abstract

Considering relative motion in two-dimensional Euclidean space, a constructive derivation is given for the one-way speed of light in a moving frame in relative motion with respect to another frame presumed to be at rest. The one-way speed is shown to be equal to c under a preferred resynchronization in the moving frame. Even if the moving frame uses the preferred synchronization convention of the presumed rest frame, the average round-trip speed remains c on any closed path in the moving frame.
