A student asks a series of questions about a wave. The answer to which question will allow the student to determine whether the wave is electromagnetic or mechanical?
Does it require a medium in order to travel?
Can it pass through air and water?
Does it have a measurable speed?

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.
