What best describes a possible transfer of energy? A mechanical wave transfers energy through matter. A longitudinal wave transfers energy perpendicular to wave motion. A transverse wave transfers energy parallel to wave motion. A sound wave does not need a medium to transfer energy through.
A wave is a transmission of a disturbance from one point to another. Wave involves transmission of energy from one point to another through a materials medium.
Waves may require or may nor require a material medium for transmission. Those wave that do not require material medium for transmission are electromagnetic waves while those that require material medium are called mechanical waves.
Mechanical waves such as sound wave transfers energy from one point which is the wave source to another point through a material medium.
