The back and forth movement of an object is called undulation, more commonly referred to as swaying or rocking. An object's undulation is measured in cycles (e.g. the number of times an object moves back and forth) per unit time. Ex. the undulation of a pendulum (such as in a grandfather clock) is usually measured in cycles per second.
Repeated back and forth and up and down motion of waves is call vibration. It is defined as an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.
Vibration. If the movement in such a way that the acceleration of the particle is directly proportional to the displacement from a fixed point and always directed towards the fixed point then it is termed as SHM ie Simple Harmonic Motion.

Oscillation.
Vibrations are back and forth movements.

Compressional Waves
A sound wave is logitudinal because the motion of the medium (air) travels in the same direction as the wave (back and forth).
Longitudinal waves consist particles in a medium (ex of a medium= air) vibrate back and forth in a parallel direction to the direction of the wave is traveling. Example of a longitudinal wave are sound waves. Boom! Opposite of longitudinal waves would be a transverse wave where instead of particles moving in a parallel direction, transverse waves vibrate in a medium, side by side perpendicular to the direction the wave travels to. Example of a transverse wave is a light wave. Hope this helped =]
Hi, sound waves vibrate particles within a certain medium, and we can consider water as a medium just like air. the way sound waves work is by transmitting energy from the source (you maybe) through a medium, which is water in this case making the particles in water vibrate back and forth to carry the energy (sound waves) in all directions, so a receiver somewhere below the water can hear a noise. i hope this answered your question :)

it is a vibration :)
The type of seismic waves that cause back and forth motions are P waves. P waves cause particles in material to vibrate back and forth.
p A+

it's called frequency. it can go up and down or back and forth
Vibrations
Waves are formed by the earth's gravity and the moon's gravitational pull. It make the back and forth motion with the water, thus forming waves.
No, they are different types of wave. Transverse waves vibrate across the direction of motion, like the waves you get when you shake a rope. Longitudinal waves vibrate back and forth along the direction of motion like a sound wave.
P -waves travel faster because the movement of them, it is a back and forth motion while S- waves are a side to side expending more energy.
