Properties of Compressional or P waves. The first kind of body wave is the P wave. This is the fastest kind of seismic wave their name derives for the fact that P is an abbreviation for primary, first wave to arrive. The P wave generally travel at speeds between 1 and 14 km/sec. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
How fast do waves travel? The speed of a wave-its wave speed-is related to its frequency and wavelength, according to this equation: wave speed (metre per second) = frequency (hertz) Ã wavelength (metre). For example, a wave with a frequency of 100Hz and a wavelength of 2m travels at 100 Ã 2 = 200m/s. Check your understanding of the equation by having a go at this activity.
