Seismic waves are vibrations generated by an earthquake. They travel along the surface of the Earth and through the earth.
They are a type of wave known as a mechanical wave and as such (unlike electromagnetic waves) require a medium through which to travel.
Seismic waves can be split into body and surface waves. The body waves can be split into two main types, the P-wave or primary wave which is a compression or longitudinal wave which can travel through solids, liquids and gasses and the S-wave which is a transverse or shear wave and can only travel through solids.
A mechanical wave is a type of wave that requires a medium, such as air or water, to travel through. Examples include sound waves and seismic waves. They transfer energy through the vibration of particles in the medium.
Since an earthquake or seismic wave is a pressure or force wave (like sound waves), it requires a material in which to propagate. So, no earthquake waves can travel through a vacuum.
The medium of a wave is the matter a wave travels through.So yeah, if you wiggle a rope, the medium isn't the air around the rope... the medium is the rope itself!
The medium through which a wave travels depends on the type of wave. For example, sound waves travel through air, water waves travel through water, and seismic waves travel through the Earth's interior. Electromagnetic waves, such as light, can travel through a vacuum, like space.
That is the phenomenon of wave compression, where the density of a medium increases as a wave passes through it. This can happen with sound waves, seismic waves, or any other type of wave that propagates through a material.
A body wave is a seismic wave that travels through Earths interior.
A disturbance that travels through a medium as a longitudinal wave is known as a sound wave. In a longitudinal wave, the particles of the medium oscillate parallel to the direction of wave propagation. Sound waves are an example of longitudinal waves as they require a medium, such as air or water, to travel through.
A wave that can travel only through matter is termed mechanical wave.
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
Mechanical wave needs a medium to travel. Examples :- Sound Wave, Seismic Wave etc.
