The molecules must be close enough to touch. They can travel through solids, liguids, and gases.

What do Mechanical wave's require?
Mechanical waves require media through which they can travel.
What does a medium seismic wave travel through?
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.
What type of wave requires a material medium through which to travel?
We know that mechanical waves require a medium through which to travel. An example of a mechanical wave is a sound (acoustic) wave. The wave transfers its energy into the medium so that it can propagate through it. In contrast, electromagnetic waves don't require a medium through which to travel. They move perfectly well through the vacuum of space.
What type of seismic wave travels through earth?
The P-wave is a compression / longitudinal wave and so unlike the S-wave is able to travel through the liquid outer core.
Does sound travel in a compressional or surface wave?
Compression
Will a primary wave travel through liquid?
Yes. Primary waves are compression or longitudinal waves can pass through solids, liquids and gasses.
What is it that sound cannot travel through?
Sound can travel through any medium. If you remove the medium you would end up with a vacuum. It is in vacuums that sound cannot travel as it needs a medium to travel (it travels as a compression wave or shear wave). Space is almost a perfect vacuum so sound is unable to travel through space.
What is the increase in density of a medium due to wave travel?
compression
What media does a transverse wave travel through?
It depends on the type of transverse wave. A transverse water wave travels through water. A transverse wave on a rope travels along the rope. A transverse electromagnetic wave, however, needs no medium. It can propagate through a vacuum.
How does a sound travel through?
Sound, which is mechanical energy, travels through a solid by setting up a mechanical compression wave in that solid. When the compression wave of the sound in air strikes the solid, it compresses the solid. It isn't much, but the energy delivered by the air is transferred into the solid. Waves of compression and rarefaction move through the solid as they did in air, but move much faster in a solid.
What type of wave cannot travel completely through water?
The S Wave (Secondary Wave) cannot travel through water. On the P Wave (Primary Wave) and the Surface Wave can travel through water.
How does sound travel through a solid?
Sound, which is mechanical energy, travels through a solid by setting up a mechanical compression wave in that solid. When the compression wave of the sound in air strikes the solid, it compresses the solid. It isn't much, but the energy delivered by the air is transferred into the solid.
