Question

What is a sessimic wave ?

Answer 1

Seismic waves are the vibrations from earthquakes that travel through the earth and can be recorded on very sensitive instruments called seismographs.Earthquakes produce three main types of seismic waves: primary(P),secondary(S) and surface(L).

Answer 2

You misspelled seismic from sessimic.

Seismic waves are waves that travel through the Earth, most often as the result of a tectonic earthquake, sometimes from an explosion. Seismic waves are also continually excited by the pounding of ocean waves and the wind. Seismic waves are studied by seismologists, and measured by a seismograph, which records the output of a seismometer, or geophone.

There are for kinds of seismic waves in two groups: P wave, S wave grouped as body waves; Rayleigh wave and Love wave, grouped as surface wave.

P waves (primary waves) are longitudinal or compressional waves, which means that the ground is alternately compressed and dilated in the direction of propagation.

S waves (secondary waves) are transverse or shear waves, which means that the ground is displaced perpendicularly to the direction of propagation.

The P and S waves are grouped as body waves. Body waves travel through the interior of the earth

Rayleigh waves, also called ground roll, are surface waves that travel as ripples similar to those on the surface of water.

Love waves are surface waves that cause horizontal shearing of the ground.

Rayleigh and Love waves are grouped as surface waves. Surface waves are analogous to water waves and travel just under the Earth's surface.

Answer 3

its waves that an equake sends out

two common types are: primary waves (p-wave) & secondary waves (s-waves)

the difference between s-waves and p-waves is that s-waves cannot travel through liquids, only solids, but p-waves travel through everything.
