Hi All,
I would like to know how can one explain the assimmetry in Doppler effect. I will illustrate what I mean.
If a source emits 440 Hz but is coming in my direction with a velocity V (measured in m/s) I will hear, let's say, 441 Hz. Now, if the source is at rest with respect to the medium and I am going in its direction with the same velocity (it is also a case of approximation, one could say), I will hear 442 Hz.
Why are these two frequencies different ?
Why one is not alowed to apply symmetry considerations here ?
Best wishes
