S-Waves
its simple. they dont
The lithosphere lies above the asthenosphere. The asthenosphere is where isostatic adjustments take place and it is a very ductile region. Seismic waves pass slower through this region of the earth than they do through the overlying lithosphere.
Seismic waves that can pass through the centre of the Earth must be capable of travelling through liquids (as the outer core is molten). As such we know that these waves are longitudinal or compression waves.
If you mean Earth's interior, only longitudinal waves can pass through the liquid parts.
Seismic waves pass through the earth when part of earth's crust breaks.
Shear waves will not pass through the molten outer core of the Earth.
Sound.
S-Waves
No, because to reach the center of the Earth, they need to pass through the outer core. Secondary waves, or S-waves, can't pass through liquids, such as the liquid outer core, so they can't thus even reach the center of the Earth.
Yes. Compressional waves (P-waves) can travel through solids, liquids, and gases. They can propagate through every layer of earth's interior. In contrast, shear waves (S-waves) can pass through solids but not liquids or gases. As they propagate toward the center of the earth they pass through the crust, refract through the crust-mantle interface, pass through the mantle, but cannot pass through the mantel-outer core interface because the outer core is liquid.

By the way earthquake waves refract as they pass through it.
This is because the Outer Core is liquid, and we know from experiments that S-waves cannot travel through liquids. If they could pass through the outer core, they could pass through the Inner, but they are absorbed by the first barrier, at the Gutenberg Discontinuity.
There is no seismic wave that can only pass through the Earth's mantle. However S-waves can not travel through earth's outer core because it is a liquid.
Because of the behaviour of seismic waves generated by earthquakes as they pass through the earth.
