'Die Ausbreitung' (spread / propagation) is the noun form of the reflexive verb 'sich ausbreiten' (to spread). It derives from the adjective 'breit' (wide) and describes the process by which something occupies a larger area or space.

The fire spread quickly throughout the whole building.
This word is often used for things that spread uncontrollably. Typical examples are the spread of a disease, a virus, a fire, or even rumors and news.
Die schnelle Ausbreitung der Nachricht überraschte alle.
The rapid spread of the news surprised everyone.
The thing that is spreading usually appears in the genitive directly after the noun or is connected with 'von' + dative. Common verbs in this context are 'verhindern' (to prevent), 'stoppen' (to stop), and 'eindämmen' (to contain).
Die Regierung will die Ausbreitung des Virus eindämmen.
The government wants to contain the spread of the virus.
In physics, 'Ausbreitung' (propagation) describes the movement of waves. If you read the word in connection with 'Licht' (light), 'Schall' (sound), or 'Wellen' (waves), this technical meaning is intended.

We are studying the propagation of sound waves underwater.
