Waves part 2

How do electromagnetic and mechanical waves compare?

• Mechanical waves can only travel through a vacuum, but electromagnetic waves can travel through a solid, liquid, or gas.

• Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a gas.

• Mechanical waves can only travel through a solid, liquid, or gas, but electromagnetic waves can travel through a vacuum.

• Mechanical waves can travel through a solid, liquid, or gas, but electromagnetic waves can only travel through a solid.
