What term describes a disturbance such as sound or light that moves through a medium or space?

Explanation:
A wave is a disturbance that propagates through a medium or space, carrying energy from one location to another. This fits sound in air and light in vacuum, since both are disturbances that travel and transmit energy without bulk matter moving with them. A pulse is a single, localized disturbance; a signal refers to information carried by a wave; and vibration is the back‑and‑forth motion of particles rather than the traveling disturbance itself. So the term that describes a disturbance moving through a medium or space is a wave.
