Question

what kind of wave requires a medium to travel through? light electromagnetic mechanical

Explanation:

To determine the wave that requires a medium, we analyze each option:

• Light is an electromagnetic wave and can travel through a vacuum (no medium).
• Electromagnetic waves (like light, radio waves) do not need a medium and can propagate in a vacuum.
• Mechanical waves (e.g., sound waves, water waves) require a medium (solid, liquid, or gas) to transfer energy as they rely on particle interactions in the medium.

Answer:

C. Mechanical
