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.
Where is the sun's energy more spread out?
The sun's energy spreads out the farther the distance from the sun.
What causes a blue shift?
Radial motion of the source toward the observer.
What is it called when waves bounce from a surface back toward the source?
reflection

What are good trees for panting around septic tanks?
arborvitae, they draw water towards themselves instead of sending roots toward the water source
If four sound waves reached a source at the same time what do the waves wave do not have in common 1 amplitude 2 frequency 3speed 4 wavelenght?
First of all, sound waves propagate away from the source, not toward it.Next, if four sound waves reached the same point at the same time, there's no reasonwhy they couldn't all have the same amplitude, frequency, speed, and wavelength.Next question ?
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.
