Properties
Primary Waves
Longitudinal Waves Pass through liquids and solids Travel faster then s-waves
Secondary Waves
Transverse Waves Can only travel through solids
Detection
When an earthquake happens the seismic waves travel through the earth
S-Wave
S-waves travel through the earth in a curve pattern, curving outwards to the sides, due to density changes in the mantle. Where s-waves can’t be detected is the s-wave shadow zone. This is due to the fact that s-wave can’t travel through liquids telling us that the earth has a liquid core.
P-Wave
P-waves also travel through in a curve pattern however they can be detected in a lager are as they can travel through the liquid core. There are still 2 small p-wave shadow zones at about
