Question

which is the best definition of a wave? a wave is a disturbance that transfers energy. a wave is a magnetic charge flowing in one path. a wave is an electric charge that flows through wires really fast.

Explanation:

A wave is a disturbance that transfers energy through a medium (or in some cases, through a vacuum like electromagnetic waves). The second option describes a magnetic charge flowing in one path which is not the general definition of a wave. The third option describes an electric charge flowing through wires fast which is more related to electric current rather than a wave.

Answer:

A wave is a disturbance that transfers energy.
