Answer:
Sound waves and light waves need to change
Step-by-step explanation:
Electromagnetic waves are waves that can pass through a vacuum. Electromagnetic waves are associated with electrical and magnetic components. They all travel at the speed of light. Energy transfer through a medium involves the absorption and re-emission of wave energy by atoms of the material. Examples: light waves, X-rays, radiation waves
Mechanical waves need a medium to travel so that they can transfer their energy from one place to another. Examples: ocean waves, sound waves, earthquake waves. Thus light waves are electromagnetic waves and sound waves are mechanical waves and thus space should be exchanged.
