Answer:

Light can travel through a vacuum

Explanation:

Light wave is an example of electromagnetic wave and the sound wave is a mechanical wave. The mechanical waves requires a medium to propagate from one point to another while the electromagnetic wave do not.

Also, the sound wave is a longitudinal wave. The light wave is the interaction of both electric and magnetic field.

So, the correct option that shows one difference between the light wave and the sound wave is (A) " Light can travel through a vacuum ".
