explains the difference between transverse and longitudinal waves - created at http://goanimate.com/

cean waves are mechanical waves; so, too, are sound waves, as well as the waves produced by pulling a string. It is important to note, again, that the matter itself is not moved from place to place, though it may move in place without leaving its position.

Harmony is the study of how sounds work together to create affects desired by the composer. When two frequencies of sound are not exactly equal in value, the loudnessof the total sound seems to oscillate or beat.

A frequency spectrum is a graph that shows the amplitudes of different  frequencies  present in sound. Amplitude or loudness, is represented on the y-axis, and frequency is shown on the x-axis. a somogram shows on the verlical axis and time on the horizontal axis. The loudness is shown by a color range.

the wavelength  of sound in air can be compared  to the size of everyday objects. as with other waves, the wavelength  of a sound is inversely related to its frequency.  different in sound are due to differences in both frequency and wavelength

object that move faster than sound are called supersonic. soud  travels through most liquids and solids faster  than through air.  sound travels about 5 times faster in water and about 18 times faster  in steel. this is because sound is traveling  oscillation. like other    oscilations sound depends on restoring forces.

An example of mechanical wave is a sound wave  Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmissionthe materialis limited.
