Doppler Effect
No change in frequency or wavelength.
Doppler shift
That's called the "Doppler effect".
The pitch becomes lower because the sound waves are no longer compressed once the source passes you.

Once the wave has left the source that generated it, the frequency can't be changed.If you happen to be moving toward or away from the source at a high enoughspeed, then the frequency of the radiation may appear to you to be changed.But it's not.
When the source of a sound moves, the frequency noted by the observer will change. This is an example of Doppler's law. answer: its pitch appears to change.
no...frequency is the property of source....
the frequency of a sound can change depending on how fast the source is vibrating
When the frequency of the vibrations that produce the sound change. Higher frequencies -> higher pitch. OR if the source of the sound is moving towards or away from you -> Doppler effect.
You can't. Once the wave leaves its source, its frequency doesn't change.
The frequencies are the same, unless the source is moving relative to the observer.
