    "abstract": "We show that when the observers are located in a plane electromagnetic wave\nit is not compulsory for them to take into account the time dilation and length\ncontraction effects when the wave is detected from two inertial reference\nframes in relative motion. We also illustrate the difference between the\napproach that uses Einstein type of observers confronted with time dilation and\nlength contraction effects and an unconventional approach that uses observers\ndetecting information from the energy that arrives at their location.",
