    Which of the following waves require a medium to

    travel?  
    A Light waves Correct Answer Incorrect Answer
    B Radio waves Correct Answer Incorrect Answer
    C Sound waves Correct Answer Incorrect Answer
    D Microwaves Correct Answer Incorrect Answer

    Solution

    Sound waves are mechanical waves, which require a medium (such as air, water, or solids) to travel.   They cannot propagate in a vacuum.   On the other hand, electromagnetic waves (like light, radio waves, and microwaves) do not require a medium and can travel through space.
