sound waves are electromagnetic waves that can only travel through a medium, while light waves are mechanical waves that can travel through a medium or through a vacuum.

Explanation:

Sound waves are mechanical, requiring a medium (like air, water) to propagate, as they rely on particle vibrations. Light waves are electromagnetic, which can travel through both media and the vacuum of space, as they do not need particles to transfer energy.

Answer:

Sound waves are mechanical waves that can only travel through a medium, while light waves are electromagnetic waves that can travel through a medium or through a vacuum.
