In the Doppler effect for sound if the source and receiver are at rest but the air is moving will there be any change in frequency or wavelength?
No change in frequency or wavelength.
What is the observed change in the frequency of a wave when either the source or observer is moving?
Doppler shift
What is the change in frequency of a wave produced by a moving source?
That's called the "Doppler effect".
If you are moving toward the source of a sound wave and then pass the source and continue moving away the will change.?
The pitch becomes lower because the sound waves are no longer compressed once the source passes you.
What is A change in the observed wavelength or frequency of a wave that occurs when the source of the wave or the observer is moving?
Doppler Effect :)

Can you change the frequency of em wave?
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.
For a stationary observer when the source of a sound is moving its?
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.
Does Amplitude change frequency?
no...frequency is the property of source....
How does sound frequency change?
the frequency of a sound can change depending on how fast the source is vibrating
When does the pitch of sound change?
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.
How can you change the frequency of a wave?
You can't. Once the wave leaves its source, its frequency doesn't change.
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.
