An example of a mechanical longitudinal wave, or a compressional wave, is a sound wave. Another example is primary waves of an earthquake. Both travel through their respective medium, either air and Earth, while the particles constituting these mediums move in the direction parallel to the wave.Continue Reading
A compression wave is a mechanical longitudinal wave. The longitudinal wave constitutes the movement of the compressed region of matter in one direction. The particles of which that matter consists, however, do not move along with the wave. They are displaced in the direction parallel to that in which the wave propagates.
To visualize a compressional wave in a nonwave example, picture a slinky toy. The compression of the spiral rings appears to be a wave traveling from one end of the slinky to another, while individual rings simply oscillate around their original points of rest.
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.Full Answer >
The bottom of a wave, or a low spot between waves, is referred to as the trough, while the top of a wave is referred to as the crest. As waves elevate, the force of gravity pulls them back down, causing the crest of a new wave to form.Full Answer >
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. The longer a sound's wavelength, the lower the pitch of that sound.Full Answer >
Sound travels through a medium as a mechanical wave. It cannot travel in a vacuum because it travels by vibrating the particles of the medium to transfer energy from one place to another.Full Answer >
