What happens in the Relativistic Doppler Effect?

Question

Any correlation to wave dispersion Phenomena?

Answer 1

Well, relativistic effects include length compression as well as mass increase and time dilation. All of these factors are scaled by the Lorentz transformation, that is the square root of (one minus the velocity squared divided by the speed of light squared). (Those parentheses were used to indicate grouping, in the mathematical sense). But for observers traveling very fast through space, the appearance is similar to a Doppler shift, where light sources ahead of the observer will appear bluer and will shift towards the direction of motion, and objects behind will be red shifted and also shift towards the axis of motion (in the opposite direction of the blueshifted objects, that is in the direction that is polar opposite from the direction of travel).

Is that what you were referring to?

Answer 2

Yes.
