Question

Which type of wave needs a medium to travel?(1 point) Responses light waves, because they travel by oscillating molecules light waves, because they travel by oscillating molecules sound waves, because they travel by oscillating molecules sound 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

Answer 1

The correct response is: **sound waves, because they travel by oscillating molecules**. Sound waves are mechanical waves that require a medium (such as air, water, or solids) to propagate, while light waves (electromagnetic waves) can travel through a vacuum and do not require a medium.
