Mechanical Waves:
1.Mechanical waves need a material medium for their propagation.
2.These waves are produced due to the vibrations of the particles of the medium.
3.They have low speed.

Electromagnetic Waves:
1.Electromagnetic waves do not need any material medium for their propagation.
2.They are caused due to change in electric and magnetic fields.
3.They have high speed.
