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.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.

For a stationary observer when the source of a sound is moving its pitch appears to change?
true
For a stationary observer when the source of a sound is moving it's pitch appears to change?
False
When a source of light approaches an observer the light appears to be than it actually is?
Blue shifted and when it is moving away it is under a red shift.

When a stationary observer when the source of a sound is moving its pitch appears to change?
true
For a stationary observer when the source of a sound is moving it's pitch appears to change?
False
What happens to a sound source as it approaches?
It appears to have a higher frequency due to the Doppler Effect.
Does speed increase for an observer that stays in one spot when the source of a sound is moving?
pitch appears to change
Is it true or false for a stationary observer when the source of a sound is moving its pitch appears to change?
True
What is an apparent in frequency of a sound source that moves relative to an observer?
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
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
