What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
Its called the doppler effect.
When a sound source is moving away from an observer the observer will hear a lower pitch. This is due to?
This is due to the Doppler effect.
When For a stationary observer when the source of a sound is moving it is?
C.pitch appears to change -apex
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

Its called the doppler effect.
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
When a sound source is moving away from an observer the observer will hear a lower pitch. This is due to?
This is due to the Doppler effect.
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 its pitch appears to change?

For a stationary observer when the source of a sound is moving it's pitch appears to change?
False
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.
How can the pitch of sound wave be raised?
It can be done by moving the sound source quickly towards the observer (or the observer towards the sound), like a siren on a speeding train, and is known as the Doppler effect.See related link.
Is it true or false for a stationary observer when the source of a sound is moving its pitch appears to change?
True
Whenever a source of sound moves the frequency heard by the observer is Less than that of the source?
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
HOW is it produce of Doppler effect?
If you have a source that emits a wave and an observer that is motionless with respect to the source, no Doppler Effect is noticed. If the source and observer move with relation to each other then the wave appears distorted (compressed if the motion is towards each other, distended if the motion is away from each other). Say we have a source of sound by the side of the road (a repeatedly clanging bell). If an observer moves towards it, the sound waves appear to meet the observer sooner and the pitch of the bell (and frequency of the clanging) increase. After passing the bell and while moving away, the frequency of the clanging and the frequency of the sound drop.
