Answer:
The vibrations of a longitudinal wave are in a direction parallel to the direction of travel.
Explanation:
Longitudinal waves are waves in which individual particles vibrate in a direction parallel to the passage of energy. If energy is delivered from one end of a medium to the other i.e from east to west, then, the medium's particles will vibrate eastward to westward.
They follow compression and rarefaction as they travel. For example, if the slinky is stretched horizontally and the first coils vibrate horizontally, each individual coil of the medium is set into vibrational motion in directions parallel to the direction in which the energy is transferred, resulting in longitudinal waves.
