explain the type of seismic wave
Answers
four type of wave
p waves =the shock wave become after the movement of two massive rock
S waves = the wave created after the reflection of primary wave
L wave = when the released energy come on the surface off the earth that time generated waves
Rayleigh waves = Rayleigh waves are the type of surface wave that travel near a solid surface
Seismic waves are fundamentally of two types, compressional, longitudinal waves or shear, transverse waves.
Through the body of the Earth these are called P-waves (for primary because they are fastest) and S-waves (for secondary since they are slower). However, where a free surface is present (like the Earth–air interface) these two types of motion can combine to form complex surface waves.
Although often ignored in introductory texts, surface waves are very important since they propagate along the surface of the Earth (where all the buildings and people are) and usually have much higher amplitudes than the P-waves and S-waves. It is usually surface waves which knock down buildings.
