Requires a medium to travel
- Mechanical: Yes — needs a material medium (solid, liquid or gas).
- Electromagnetic: No — does not require a medium; can travel through vacuum.
Can be longitudinal or
- Mechanical: Can be longitudinal or transverse (or a combination/surface wave).
- Electromagnetic: Essentially transverse in free space (longitudinal components occur only in special cases like plasmas or waveguides).
Example of longitudinal wave
- Mechanical: Sound waves; P (primary) seismic waves.
- Electromagnetic: Generally none in free space (only special circumstances such as waveguide or plasma modes).
Can travel through
- Mechanical: Solids, liquids, gases (cannot travel through vacuum).
- Electromagnetic: Vacuum as well as materials (air, glass, etc., with possible absorption/reflection).
Examples
- Mechanical: Sound, water (surface) waves, seismic waves.
- Electromagnetic: Radio, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays.
Quick summary: Both types transport energy (not bulk matter). Mechanical waves require a medium and may be longitudinal or transverse; electromagnetic waves do not require a medium and are transverse in free space.
