Correct answer: "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space."
Explanation: Mechanical waves need a material medium (solid, liquid, or gas) to propagate (examples: sound, waves on a string). Electromagnetic waves are oscillating electric and magnetic fields and can propagate through vacuum (examples: light, radio, X‑rays).
