How do sound waves spread or propagate from the source toward the space around it?
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.

When a source of sound moves toward a person what does pitch do?
As sound travels, the waves spread out and lose energy. Since the energy of a sound wave is proporitonal to it's total energy, losing energy causes the frequency to decrease. Pitch is human perception of frequenct, so the pitch drops as the waves propagate.
Which refers to the change in wavelength tht occurs when an object moves toward or away from a source?
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.
What is it called when waves bounce from a surface back toward the source?
When waves bounce from a surface back toward the source, it is called reflection. This phenomenon occurs when waves encounter a boundary and return in the opposite direction.
What happens to sound waves when the source of a sound is moving toward you?
When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
What happens if a source is moving toward you at a high rate of speed?
If a source is moving toward you at a high rate of speed, you would perceive an increase in its frequency, resulting in a higher pitch (Doppler effect). This is commonly experienced with emergency vehicles approaching with sirens on.
How do sound waves propagate from the source towards the space around it?
what kind of the source toward the space around it

A source generates favorable cognitive thoughts toward the source of a message?
Source Bolsters.
What are good trees for panting around septic tanks?
arborvitae, they draw water towards themselves instead of sending roots toward the water source
What was president Truman’s policy for dealing with the spread of communism?
The president adopted a policy of containment toward Soviet expansion and the spread of communism
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.
What best describes the reaction of many American colonists toward British colonial policy following the French and Indian War?
it started in india and spread to other countries around the world
