They move back and forth - in this case, along the direction in which the wave advanced.
longitudinal wave
Longitudinal wave
In a longitudinal wave, the particles in the medium move back and forth along the path of the wave. Sound passing through a solid, liquid or gas is a good example of a longitudinal wave. Waves produced by the wind blowing on the surface of a pond are not longitudinal (The water particles actually move in overlapping vertical circles.) nor are the waves in a flag flapping in the breeze.
If you hold the ends of a slinky toy so that it is stretched out horizontally you can demonstrate excitations of both transverse and longitudinal waves. If you move one end of the slinky up and down in a periodic fashion you will see transverse waves. If you move one end of the slinky in and out along the horizontal direction that it is stretched out in, you will excite longitudinal waves.

That would depend on many factors. Length, thickness, density, resonance....too many factors to take a stab at an answer.

When the circular muscles contract, they make the worm skinnier. When the longitudinal muslces contract, they make the worm shorter. This series of movements allows for the worm to move forward.

Bones are not essential for locomotion . Earthworm move by using circular and longitudinal muscles along with setae and shoe accordion like locomotion .
