light waves, because they travel by oscillating molecules

Answer 1

The correct response is:

**sound waves, because they travel by oscillating molecules.**

Sound waves require a medium (solid, liquid, or gas) to propagate, while light waves can travel through a vacuum as they are electromagnetic waves.
