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.
The fastest thing in the whole. universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 10 8. m/s. Light. travels in waves , and we call this traveling propagation . Propagation of waves has both a speed and a. direction, called the velocity . The velocity of light changes depends on the material it travels through. Light waves can be changed in a few different ways. Reflection is when the waves bounce off a. surface and change direction, like when they hit a mirror or pool of water.
