Describe L-waves

1.	Describe L-waves
Answer» Four types of seismic waves\| Specifications of all types of seismic waves.\tP- Waves (Primary waves)\tS- Waves (Secondary waves)\tL- Waves (Surface waves)\tRayleigh waves.\xa0L\xa0waves they are dispersive so the particular speed at which they travel depends on the wave period and the near-surface geologic structure, and they also decrease in amplitude with depth. Typical speeds for Rayleigh waves are on the order of 1 to 5\xa0km/s.<br>Wave\xa0is a flow or transfer of energy in the form of oscillation through a medium – space or mass. Sea\xa0waves\xa0or tides, a sound which we hear, a photon of light travelling and even the movement of small plants blown by the wind are all\xa0examples\xa0of different types of\xa0waves.
