It moves perpendicularly to the movement of the source, it consists of crests (the part above the mid-line), troughs ( the part that is below the mid-line ). read more
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave propagation. read more
In longitudinal waves the “object” which “waves” moves parallel to the direction of the wave. In transverse waves the “object” changes perpendicular to the direction of the wave. And by “object” I mean basically anything - particles, vectors of electomagnetic field or the probability in a wave function. read more
While all waves share some basic characteristic properties and behaviors, some waves can be distinguished from others based on some observable (and some non-observable) characteristics. It is common to categorize waves based on these distinguishing characteristics. read more
