    Waves in which the oscillations are parallel to the direction of energy transfer, giving compressions and rarefactions.
    AQA · Transverse and longitudinal waves (study guide)
    Waves in which the particles oscillate backwards and forwards along the same line that the wave travels.
    AQA · Transverse and longitudinal waves (study guide)
