Question

select the correct answer. which phrase best describes wave motion? a. movement of energy through space or a medium b. movement of matter through space c. movement of energy within a particle d. movement of air molecules through a medium

Explanation:

A wave is the transfer of energy through space or a medium without the net movement of matter. Option A correctly describes this as the movement of energy through space or a medium. Option B is incorrect because waves do not involve the movement of matter through space in the same sense. Option C is wrong as waves are not about energy movement within a particle. Option D is too specific to air - molecules and does not capture the general concept of wave motion.

Answer:

A. movement of energy through space or a medium
