The speed of light in free space is independent of the motion of its source and of the motion of the observer.
A consequence of this postulate is that all observers will measure lightspeed the same, regardless of their motion or of the motion of the source. While we can say that all observers will measure lightspeed the same, we cannot say that they will each measure the same frequency and wavelength, in all conditions as described above? In fact the motion of the source and detector is accounted for by the variance in the observers measure of frequency and wavelength. The functionality of the Lorentz transformation equation results from the ceiling on lightspeed and not from its constancy of measure. A postulate is an assumed truth. -- You received this message because you are subscribed to the Google Groups "Epistemology" group. To post to this group, send email to [email protected].
