when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

if you look up in the top right corner you'll see your current profile picture, click than click "view profile" you'll be able to change it there.

not always but somethings can be reproduced in a laboratory.
