Energy transfer through space as a wave without requiring a medium is characteristic of which type of waves?

• A. Water Waves
• B. Sound Waves
• C. Mechanical Waves
• D. Electromagnetic Waves

Answer: (D)

Energy moving through space without a material medium describes electromagnetic waves, which propagate as changing electric and magnetic fields that sustain each other even in vacuum. Because of this, they can travel through empty space—light, radio waves, and X-rays are examples. In contrast, water waves and sound waves are mechanical waves that require a medium (like water or air) to transfer energy. So this description points to electromagnetic waves.
