Acoustic

DEFINITIONS Is the rate at which the phase of the wave propagates in space. Frequency is the number of occurrences of a repeating event per unit time the wavelength of a sinusoidal wave is the spatial period of the wave – the distance over which the wave's shape repeats. Longitudinal waves are waves that have the same direction of vibration along their direction of travel, which means that the vibration of the medium (particle) is in the same direction or opposite direction as the motion of the wave. A transverse wave is a moving wave that consists of oscillations occurring perpendicular to the direction of energy transfer.
