  • Relativistic Doppler effect

    Relativistic Doppler effect

    Relativistic Doppler effect.  There is an apparent shift in the observed frequency of any electromagnetic wave (light) when there is any relative motion between the source of light and the observer. This can be easily determined by using the 4-vector formulation of theory of relativity. Lets discuss the details of this phenomena under two situations.…

  • Moving clocks run faster in the Doppler hemisphere of approach

    Moving clocks run faster in the Doppler hemisphere of approach, run slower in the Doppler hemisphere of recession and run slower in the Doppler plane of intersection of hemisphere of approach and recession. The GPS satelites eg are in constant free fall towards earth and located in the Doppler plane of intersection, they never approach…

  • The different kinds of time dilation, invariance of proper-time and principle of equivalence

    For 2nd effect if the speed is negative that is source and observer are in relative approach the effect will always be anti-red shifted or as is known violet-shifted, again a distribution in angle which is extended towards translational vantage and line of sight vantage. (perpendicular to line of sight that is) The 3rd effect
