Explanation

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'. S-wave moves as a shear or transverse wave. So, motion is perpendicular to the direction of wave propagation. L-waves and Rayleigh waves both are types of surface waves.
