Question 14 • Physics

What best describes a possible transfer of energy?

Answer
A
A longitudinal wave transfers energy perpendicular to wave motion.
B
A transverse wave transfers energy parallel to wave motion.
C
A mechanical wave transfers energy through matter.
D
A sound wave does not need a medium to transfer energy through.

Explanation

Mechanical waves transfer energy through matter, such as air, water, or a solid. Sound is a mechanical wave, so it needs a medium; in a longitudinal wave, particles vibrate parallel to the wave’s direction, while in a transverse wave they vibrate perpendicular to it. Therefore, “A mechanical wave transfers energy through matter” is the best description.
