D
Can the wave travel through a vacuum?
why?
Rebecca can ask if the wave can travel through a vacuum because electromagnetic waves are able to propagate through empty space, whereas other types of waves, such as mechanical waves, require a medium (such as a solid, liquid, or gas) to travel through. Therefore, if the wave can travel through a vacuum, it is likely to be electromagnetic in nature.
