How does sound frequency change?
the frequency of a sound can change depending on how fast the source is vibrating
How is frequency made?
To make sound frequency change alter the pitch.
What do you call the change in sound frequency due to a relative motion?
The Doppler Effect.
When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?
If there is no relative velocity between source and listener, there will be no change in frequency.
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.

A train passes by blowing its whistle As it passes the sound of the whistle is lower than it was on its way towards you This is due to?
a change in the sound's frequency caused by the motion of the sound's source
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.

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.
The change in pitch of a sound caused by motion of either the sound source or receiver is known as what?
Doppler Effect
Why is there a change in sound tones as a car moves by?
There are changes in the frequency of the sound waves caused by the motion of the car, which demonstrates the Doppler Effect.
