What else can I help you with?
Why doesn't the Doppler shift appear when an observer moves toward the source?
Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.
What is the imagenary point in the sky directly above an observer on Earth?
That's the observer's 'zenith'. Since it's referenced to the "observer's head", each observer has a different zenith.
Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
Does the Doppler Effect mean that an observer ahead of a train hears the train at a higher frequency sound than an observer behind the train?
Yes that is the case.
How does the frequency measured in front of the source appear to the observer compared to the frequency measured from behind?
The frequencies are the same, unless the source is moving relative to the observer.
