Expert Solution

traveling wave

an organized disturbance traveling with a well-defined wave speed

???

transverse wave

the disturbance occurs perpendicular to the direction of travel of the wave (wave on a string, EM waves)

???

longitudinal wave

the disturbance occurs parallel to the direction of travel of the wave (sound waves)

???

mechanical waves

(water waves, sound waves, shock waves) require a medium in which to travel; a disturbance generated by a source, travels through a medium and transfers energy (but not matter)

====================================================================================

n a longitudinal wave, the motion of the medium is parallel to the direction of the wave . This means that the particles move left and right which in turn makes the other particles start to oscillate. Sound waves are longitudinal waves.

Another example of a longitudinal wave is a P wave or primary wave during an earthquake. P waves are also known as compressional waves, because of the pushing and pulling they do

A transverse wave is a wave in which the motion of the medium is a right angles to the direction of the wave.

A wave on a rope is a transverse wave. Light and other electromagnetic waves are also transverse waves.

Another type of transverse wave is the S wave or secondary wave, which is the second wave you feel in an earthquake
