Propagation of disturbance suffered by a particle in a medium is called wave propagation Wave Propagation is a term used to estimate the actions and characteristics of a wave of motion either in solids, liquids, gasses, or electrical radio type waves by the environment it is in and what factors affect those waves behaviors.
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
A longitudinal wave is a scalar wave with the vibration parallel to the central direction of propagation.
Wave is a propagation of oscillations of some physical parameter (perturbation of pressure, mass density, electrical or magnetic fields...). If oscillations are perpendicular to the direction of propagation - the wave is transverse (for example - electromagnetic wave). If physical parameter oscillates along the propagation direction - the wave is longitudinal(Sound).
Ground wave, sky wave and space wave propagation
Ground Wave propagation is sometime unreliable due to the conditions at the surface or topography that the ground waves may encounter. Iron deposits, humidity or water )lack of or over abundance of) ,vegetation etc. On the other hand when using ground wave propagation in barren terrain can be used quite effectively because of the lack of variables. Propagation over large bodies of water (Atlantic, Pacific Oceans) is relatively reliable.
S waves, or secondary waves, are transverse seismic waves, meaning that the particles being effected by the wave are moving perpendicular to the wave's propagation.
Modes of Propagation = different ways to continue and/or increase the number of a given species. Example: sexual reproduction.
Wave propagation

Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question
... wave's speed of propagation.
"Propagation" means the process of the wave getting from here to there.
Frequency and speed of propagation of the wave are independent of one another. The medium determines the speed of propagation.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
