When comparing and contrasting EM mechanical waves

Electro magnetic waves are the waves which are produced with vibration of the particles which are charged.

Explanation:

Electromagnetic waves are created by the vibration of charged particles. A mechanical wave is a wave that isn't equipped for transmitting its vitality through a vacuum.

Mechanical waves require a medium so as to ship their vitality starting with one area then onto the next. A sound wave is a case of a mechanical wave. Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum
