a wave with a direction of propagation that is perpendicular to its direction of oscillation
a wave with a direction of propagation that is parallel to its direction of oscillation
any speed that is faster than the speed of sound in the substance of interest
the sound produced as a result of an object traveling at Mach 1 or above
an indication of how high or low a sound is which is primarily determined by the frequency of the sound wave
