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?

• Does it have a measurable frequency?

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.
