A Rayleigh wave is a seismic surface wave causing the ground to shake in an elliptical motion(they move in a surafce rolling manner). A seismic wave means a earthquake wave, so Rayleigh wave is realted to the motion of earth and its crust. Rayleigh waves are formed when the particle vibrate with the combination of both transverse and longitudinal waves. This vibration gives rise to a wave which moves elliptically backwards that is Rayleigh Wave. Rayleigh waves are really fast they move with the spped 10 times faster than the speed of light. Rayleigh waves are generated by the interaction of P or compressional and S or shear waves(P ans S Waves are inside the Earths Crust) at the surface of the earth.
<h2>_____________________________________</h2>Love waves or Q waves or Quer Waves are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. A Love wave is a surface wave having a horizontal motion only. Love waves are formed when the earth particles move in a transverse wave manner creating a wave travelling perpendicular to the direction the wave.
