but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. This causes the waves to travel in curved paths. When the waves cross the ...

In this situation, there may be three P waves to one QRS complex, then a quick change to two P waves to one QRS complex, and so on; any combination of P waves to QRS complexes can occur.

The core itself consists of a solid inner core and a liquid outer core. There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their ...
