The relativistic Doppler effect takes into account the special relativity concept of time dilation and also does not require a medium of propagation to be used as a point of reference (light does not require a medium for propagation). 5
Relativistic kinetic energy is given as where
Classical kinetic energy is given as
At low velocities , a binomial expansion and subsequent approximation of gives:
or
Substituting in the expression for gives
Hence, relativistic kinetic energy becomes classical kinetic energy when .
