Answer: Sound waves and light waves need to change
Explanation:-
Electromagnetic waves are waves which can travel through the vacuum. electromagnetic waves have electrical and magnetic component associated with them. They all travel with the speed of light.The energy transport through a medium involves the absorption and re emission of the wave energy by the atoms of the material. Example: Light waves, X rays, Radiation waves
Mechanical waves require a medium to travel so that they can transport their energy from one location to another. Example: Ocean waves, sound waves , Earthquake waves
Thus light waves are electromagnetic waves and sound waves are mechanical waves and thus should exchange places.
