Imagine you're at the beach, observing waves. How do the waves you see (mechanical) compare with the sunlight reaching you (electromagnetic)?

• 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.
