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

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
