SUMMARY
The discussion clarifies the differences between two Doppler Effect formulas: the relativistic velocity addition formula, u = (v + u') / (1 + vu'/c²), and the frequency change formula, f' = f √[(1 + v/c) / (1 - v/c)]. The first formula describes how velocities combine in a relativistic context, while the second formula calculates the observed frequency of a wave emitted by a source moving towards a detector. Both formulas are essential for understanding the Doppler Effect in physics.
