In a longitudinal wave, particles of the medium move back and forth in the same direction as the wave. Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. The closer together the particles are, the greater the amplitude of the wave.

Do longitudinal waves have amplitude and wavelength?

The wavelength in a longitudinal wave is the distance between two consecutive points that are in phase. The wavelength in a longitudinal wave refers to the distance between two consecutive compressions or between two consecutive rarefactions. The amplitude is the maximum displacement from equilibrium.

Does a longitudinal wave such as a sound wave have an amplitude?

Does a longitudinal wave, such as a sound wave, have an amplitude? Yes. All wave types-transverse, longitudinal, surface-have all of these properties: wavelength, frequency, amplitude, velocity, period. At a football game, the "wave" might circulate through the stands and move around the stadium.
