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.
