Which type of wave can travel without a medium?

Explanation:
Electromagnetic waves can travel without a medium because they propagate as oscillating electric and magnetic fields that regenerate each other as they move. This means they don’t need air, water, or any solid to carry energy through space. That’s why sunlight travels through the vacuum of space and radio waves can reach us without a surrounding medium. In contrast, mechanical waves—like sound or water waves—require particles of matter to transfer energy, so they can’t travel in a vacuum. Wavelength is a property of a wave, not a separate type, and diffraction describes how waves bend around obstacles or through openings.
