Which type of wave needs a medium to travel?(1 point)
Responses
sound waves, because they travel by oscillating molecules
sound waves, because they travel by oscillating molecules
light waves, because they travel by oscillating molecules
light waves, because they travel by oscillating molecules
sound waves, because they travel by oscillating electromagnetic fields
sound waves, because they travel by oscillating electromagnetic fields
light waves, because they travel by oscillating electromagnetic fields
None of these responses are correct.
The correct answer is: sound waves, because they require a medium (such as air, water, or solids) to travel through. Light waves, on the other hand, can travel through a vacuum and do not require a medium.
