A P-wave is a type of seismic wave that can travel through a continuum. A P-wave can also be referred to as a compressional wave, a primary wave or a pressure wave. More »

Compressional waves are waves that move along the direction of propagation in a back and forth motion. Common examples of compressional waves include sound waves and P waves, which are types of seismic waves. More »

A transverse wave is one where the displacement of the medium in which the wave is travelling is perpendicular to its propagation. A pond ripple is an example of a transverse wave. More »

The medium of a wave is any substance that carries the wave, or through which the wave travels. Ocean waves are carried by water, sound waves are carried by air, and the seismic waves of an earthquake are carried by rock... More »

A sound wave takes on the form of a longitudinal wave. Sound waves are also classified as mechanical waves since they require a medium to travel through. More »

Because sound is a mechanical wave initiated by an object's vibration, it is propagated by subsequent molecular collisions. Once the colliding air particles hit the eardrum, several internal structures vibrate. These vib... More »

Pitch is determined by the frequency of a wave, and frequency is the combination of wavelength and speed at which the wave is traveling. Sound has a constant speed of 343 meters per second, so wavelength dictates pitch. ... More »
