On the spectral shift and the time delay of light in a Rindler accelerated frame

TL;DR

This paper explores how the gravitational spectral shift and light time delay, predicted by general relativity, also manifest in Rindler accelerated frames without gravity, confirming Einstein's equivalence principle.

Contribution

It demonstrates that key relativistic effects occur in accelerated frames absent gravity, supporting the equivalence principle with theoretical analysis.

Findings

Spectral shift occurs in Rindler frames without gravity

Time delay of light is observed in accelerated frames

Results align with Einstein's equivalence principle

Abstract

We discuss two effects predicted by the general theory of relativity in the context of Rindler accelerated observers: the gravitational spectral shift and the time delay of light. We show that these effects also appear in a Rindler frame in the absence of gravitational field, in accordance with the Einstein's equivalence principle.
