Awave is traveling through a medium. as it travels, it displaces particles of matter in the same direction as the wave is traveling. this type of wave is a longitudinal wave because the particles move parallel to the direction that the wave is traveling. transverse wave because of the way the particles are displaced as the wave passes through. longitudinal wave because it moves forward through a medium causing the particles to vibrate. transverse wave because it is not traveling in a vacuum and the particles are moving.

Answer

longitudinal wave because the particles move parallel to the direction that the wave is traveling.

Explanation

There are 2 types of a wave, electromagnetic and mechanical wave. These waves can also be categorized into two, longitudinal ans transverse waves.

longitudinal wave is a wave whose particles vibration is in the direction of wave travel.

Transverse wave is a wave whose vibration of particles is perpendicular to the direction of wave travel.
