The true statement is:
**Mechanical waves require a medium to travel through, but electromagnetic waves do not need a medium.**
Mechanical waves, such as sound waves and water waves, need a material medium (like air, water, or solids) to propagate. In contrast, electromagnetic waves (such as light waves, radio waves, and X-rays) can travel through a vacuum and do not require a medium.
