Lorentz transformation, time dilation, length contraction and Doppler Effect - all at once
Bernhard Rothenstein, Stefan Popescu
We present a simple derivation of the Lorentz transformations for the space-time coordinates of the same event. It is based on the relative character of length and time interval as…
Relativistic electrodynamics as an extrapolation of relativistic kinematics
Bernhard Rothenstein, Stefan Popescu
After having identified all the possible relationships between the electric field and the magnetic field in a given inertial reference frame we derive the transformation equations…
A generic rule that simplifies the derivation of the transformation equations accounting for the properties of the photon
Bernhard Rothenstein, Stefan Popescu
We show that the transformation equation for the tardyon velocity involves two generic functions which in turn depend on the relative velocity of the involved reference frames, on…
Lorentz transformation by mimicking the Lorentz transformation
Bernhard Rothenstein, Stefan Popescu
We show that starting with the fact that special relativity theory is concerned with a distortion of the observed length of a moving rod, without mentioning if it is a "contraction…
Counting energy packets in the electromagnetic wave
Stefan Popescu, Bernhard Rothenstein
We discuss the concept of energy packets in respect to the energy transported by electromagnetic waves and we demonstrate that this physical quantity can be used in physical proble…
Learning more from the Lorentz transformations
Stefan Popescu, Bernhard Rothenstein
Admitting the validity of Lorentz transformations for the space as time coordinates of the same event we derive their differential form in order to underline the correct prerequisi…
