Lesson plan
P wave
In continuum mechanics, a P wave (primary wave or pressure wave) is one of the two main types of elastic body waves or seismic waves. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P waves may be transmitted through gases, liquids, or solids.
