its simple. they dont
Seismic waves than changes direction and speed because of the matter it's passing through and the moving from different matter's (Inner core-Outer core)
They go faster through the inner core than the liquid outer core
the inner core is a solid
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.
When the P wave strikes the inner core it bends and goes in a different direction.

While S waves (shear waves) can travel through earth's solid inner core, they cannot travel through earth's liquid outer core, which surrounds the inner core.So, unless the S waves originated inside the inner core (which seems unlikely) there are no S waves traveling through earth's inner core.

no
We do not see shear (S) waves passing through the outer core. Because liquids can not be sheared, we infer that the outer core is molten. We do, however, see waves that travel through the outer core as P waves, and then transform into S waves as they go through the inner core. Because the inner core does transmit shear energy, we assume it is solid.

The inner core is believed to be solid, based on scientific observations of seismic waves.
They believe that because of the waves moving faster through the inner core than the outer core
