Question

12 how do electromagnetic and mechanical waves compare? a mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a gas. b mechanical waves can only travel through a solid, liquid, or gas, but electromagnetic waves can travel through each of these as well as a vacuum (or empty space). c mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a solid. d mechanical waves can only travel through a vacuum, but electromagnetic waves can travel through a solid, liquid, or gas

Explanation:

Mechanical waves require a medium (solid, liquid, or gas) to travel as they rely on the vibration of particles in the medium. Electromagnetic waves are composed of electric and magnetic fields and can travel through a vacuum as well as through solids, liquids, and gases.

Answer:

B. Mechanical waves can only travel through a solid, liquid, or gas, but electromagnetic waves can travel through each of these as well as vacuum (or empty space).
