What is an apparent lowering of pitch because the sound source is moving?
This is a Doppler shift. Pitch appears lower when an object moves away from the observer.
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
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 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 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.
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.
The Doppler effect says that if v0 is greater then vs then an observer will hear a higher pitch in front of source does that mean if vs is greater v0 an observer will hear a higher pitch BEHIND source?
Yes. vs > v0 and you're behind the source means you're catching up to it. Only the relative motion matters for the Doppler effect. Even though you're behind the source and it's moving away from you in absolute terms, you're moving toward it in relative terms.
What causes light to be shifted?
It is the Doppler effect and is caused by the light source or the observer moving towards or away from each other. In basic terms, if the two are moving toward each other then the light waves arrive at the observer more closely packed than when they left the source. That is, the wavelength is shorter and the light becomes shifted towards the blue end of the spectrum. If the two source and observer are moving apart then you get a red shift.This is analogous to the pitch of a siren which drops as the vehicle passes you and starts receding from you.
When a sound source approaches the pitch you hear is higher than when the source is not moving?
Yes. This is called a blue shift, and is caused by shortening of the period of waves. It's inverse is a red shift, which occurs when the observer is moving further away from the source of sound. These are both examples of Doppler Shifts.
