5. Types of Waves

Difference Between Mechanical Wave and Non-Mechanical Wave

Mechanical Waves vs Non-Mechanical Waves
Mechanical WaveNon-Mechanical Wave
Mechanical waves are waves that need a medium for propagation.Non-mechanical waves are waves that do not need a medium for propagation.
Sound waves, water waves and seismic waves are some examples of mechanical waves.The electromagnetic wave is the only non-mechanical wave.
Mechanical waves cannot travel through vacuumNon-mechanical waves can travel through vacuum

Matter Wave

  • This concept is a little complicated to understand. The dual nature of matter; its ability to exist both as a particle and a wave was first brought to light by the founders of the field of Quantum Physics.
  • For example, a beam of electrons can be diffracted just like any other beam of electromagnetic radiation or water wave. This property of matter was brought forward by Louis de Broglie’s Hypothesis.
