Creeping wave is a vibration. Ideal shape of a wave will follow the motion sinusoide. Apart from electromagnetic radiation, and possibly gravitational radiation, which can run through a vacuum, there are also on medium wave (which is due to change in form can produce restoring forces which flexure) where they can walk and can transfer energy from one place to another without causing particle medium migrate permanently, ie no mass displacement. In fact, every special point oscillates around a certain position.
A medium is called:
1. linear if the waves are different in every particular point in the medium can be summed,
2. limited, if limited, but it is called infinite
3. uniform if its physical characteristics do not change at different points
4. isotropic if the physical characteristics of the "same" in different directions
