Einstein's relativistic Doppler formula
Pierseaux Yves
TL;DR
This paper examines Einstein's relativistic Doppler formula, highlighting a peculiar aspect where the Doppler shift transitions from blueshift to redshift at a certain relative velocity for fixed angles.
Contribution
The paper identifies and analyzes a unique behavior in Einstein's relativistic Doppler effect related to shift reversal at specific velocities.
Findings
Doppler shift can change from blueshift to redshift at a critical velocity.
The transition depends on the angle of incident light.
The phenomenon reveals a non-intuitive aspect of relativistic Doppler effects.
Abstract
We note that Einstein's relativistic Doppler formula presents a strange aspect. For incident light received under a fixed non zero angle, the Doppler shift will change from blueshift to redshift (or vice-versa) for some critical relative velocity of the observer and the source.
