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)
Because since secondary waves cannot pass through liquids or solids, and the waves can't pass thruogh the outer core than that means that the outer core is not soild.
S-Waves
there are convection currents in the upper core.
Most of them, as the Earth's inner core is equivalent to that of the sun.
They go faster through the inner core than the liquid outer core.

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.
S waves cannot pass through the outer core. P waves can pass through both outer and inner core.
Shear waves will not pass through the molten outer core of the Earth.
There are two types of waves. There are S waves (sheer waves) and P waves (compressional waves). The S waves won't travel through the outer core because it's a liquid, but the P waves will go through it and continue going through the inner core as well.
'S' or shear waves can not pass though the liquid portion of the earth's core and the core casts a shadow. Thus as S-waves don't penetrate the outer core, they're shadowed everywhere more than 104° away from the epicentre of the earthquake.
