Question

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.

Explanation:

• Mechanical waves require a medium (matter) to transfer energy.
• Longitudinal waves transfer energy parallel to wave motion, not perpendicular.
• Transverse waves transfer energy perpendicular to wave motion, not parallel.
• Sound waves (a type of mechanical wave) need a medium to transfer energy.

Answer:

A. A mechanical wave transfers energy through matter.
