A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction which the wave moves.
As u see in the figure above, it can b represented by motion of springs forward & backward i.e the particles move parallel with the direction of the wave. The result of such longitudinal vibrations is the creation of compressions and rarefactions. Compression is the part of the spring motion which is 'rapat2'. Kalau nak faham better, Cuba try to watch this..

Now, can u compare the different between transverse & longitudinal wave??
Then check this video.. u'll see the different.
