A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound
vibrates longitudinally; the longitudinal movement of air produces pressure fluctuations.
is able to reflect off fixed ends and interfere with incident waves
is like all waves; it is able to bend into the regions of space behind obstacles.
waves have a speed that is dependent only upon the properties of the medium.
is more dense than air and thus has more inertia, causing the bunching up of sound.
A sound wave is different than a light wave in that a sound wave is
produced by an oscillating object and a light wave is not.
capable of existing with a variety of frequencies and a light wave has a single frequency.
not capable of diffracting and a light wave is.
not capable of traveling through a vacuum.
