Sound Waves vs. Electromagnetic Waves: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 7, 2024
Sound Waves are mechanical waves requiring a medium for propagation. Electromagnetic Waves are waves of electric and magnetic fields, propagating without a medium.

Key Differences

Sound waves are mechanical waves that travel through a medium like air, water, or solids. Electromagnetic waves, in contrast, do not require a medium and can travel through a vacuum.

The speed of sound waves varies depending on the medium, being faster in solids than in air. Electromagnetic waves travel at the speed of light, which is constant in a vacuum.

Sound waves are longitudinal waves, where the particle displacement is parallel to the direction of wave propagation. Electromagnetic waves are transverse waves, with electric and magnetic fields oscillating perpendicular to the direction of travel.
